The development of Goospery is closely linked to Mercury Corporation, a South Korean mobile accessories company that has marketed products under both the MERCURY and GOOSPERY names. While one company profile states that Mercury was established as a mobile phone case manufacturer in 2005, another corporate directory lists the current corporation as being established in 2011. This distinction suggests a difference between the original business operations and its later formal corporate registration.1

Trademark records provide specific dates for the Goospery brand itself. The M GOOSPERY mark was in use for mobile phone accessories by 2012, while the standalone GOOSPERY trademark in the United States records a first commercial use date of February 26, 2013. The U.S. trademark was subsequently registered to Mercury Corporation Ltd. in 2015.2 These records establish Goospery as a brand originating from the early smartphone era rather than a recent market entrant.

Mercury Corporation Ltd. is a South Korean company focused on the mobile accessories sector. Its product categories have included phone cases, protective films, chargers, earphones, phone straps and holders. The corporate website identifies the legal entity as Mercury Corporation and explicitly associates it with the Goospery name.3

Historical company profiles state that Mercury exported MERCURY/GOOSPERY products to more than 60 countries and supplied accessories for devices from manufacturers including Samsung, Apple, LG, Sony and HTC. At the time these profiles were published, the company described its production capacity as reaching up to 90,000 pieces per day. It should be noted that these figures represent historical claims rather than necessarily current production statistics.4

Current Korean corporate information lists the company’s address in Gimpo, Gyeonggi-do, South Korea, whereas older international trade listings placed its headquarters in Seoul.5

Goospery is primarily recognised for its smartphone cases. Over the years, the brand has produced cases for a wide range of Apple iPhone and Samsung Galaxy devices, alongside models from other manufacturers.

Silicone and jelly cases

The brand has extensively sold soft cases made from flexible materials, particularly through its Mercury Silicone, Jelly and Soft Feeling Jelly lines. These cases typically focus on lightweight protection, grip, flexible construction, slim profiles, colour variety and edge protection.6 Marketplace listings continue to feature Mercury Silicone, Jelly and Soft Feeling Jelly cases for various smartphone models.7

Diary and wallet cases

A significant product category for Goospery has been the diary or folio case. These designs combine a phone shell with a folding cover and often include credit card slots, ID storage, cash compartments, stand functionality, magnetic closures and screen protection. The Blue Moon Diary series is a notable example, characterised in retail descriptions as a wallet-style case with integrated storage and stand features.8

Flip cases

Goospery has produced numerous flip and folio covers in both leather-style and synthetic materials. Historical product listings include the Goospery Leather Flip Diary Cover, Techno Flip Cover, Fancy Diary Cover, Easy View Cover, Viva View Cover, Sonata View Cover and Focus View Cover.9 This category was particularly prominent during the early-to-mid smartphone era when flip and wallet cases were widely used.

Protective and bumper cases

The brand has also manufactured conventional protective cases, including bumper designs that combine different materials. A historical example is the I-Pocket Premium Bumper Case, which utilised a combination of TPU and polycarbonate and incorporated a rear card pocket.10

Other mobile accessories

Goospery trademark registrations cover a broader range of products beyond phone cases, including protective films, phone chargers, earphones, phone straps, phone holders, batteries and charging cables. For instance, the Canadian GOOSPERY trademark is registered for phone cases and several of these accessory categories.11

Goospery’s identity has traditionally occupied a space between fashion accessory and protective technology product. Rather than focusing exclusively on rugged or military-grade protection, many products aim to integrate the phone case into the user’s personal style. Historical company descriptions emphasise quality, stylish design, competitive pricing and responsiveness to changing consumer demand.12

This approach is evident in older product families that frequently offered numerous colour options and incorporated features such as card storage, viewing windows, kickstands and magnetic closures. The core value proposition can be summarised as protection combined with fashion and everyday functionality.

Depending on the specific product line, Goospery cases have utilised materials including:

• TPU: A flexible thermoplastic material commonly used for shock absorption.
• Polycarbonate (PC): A rigid plastic used for structural protection.
• Silicone.
• Synthetic or leather-style materials.
• Jelly-style flexible materials.

Some products employ multiple materials simultaneously. For example, the historical I-Pocket Premium Bumper used an inner TPU layer combined with an outer polycarbonate shell.13 This multi-material approach allows the brand to cater to different needs, ranging from thin everyday cases to more robust bumper-style designs.

Goospery is fundamentally associated with South Korea rather than being a generic label. Mercury Corporation’s corporate information identifies South Korea as its base, and Canadian trademark documentation identifies Mercury Corporation Ltd. as a Korean company with an address in Gimpo-si, Gyeonggi-do.14

Historical company materials specifically promoted Korean manufacturing capabilities and the use of domestic moulding technology.15 However, as with many international accessories brands, the manufacturing location of individual products may vary between product generations and markets, distinct from the brand’s country of origin.

Goospery has maintained an international presence for many years. Historical export profiles listed markets across Europe, North America, South America, Asia, the Middle East and Africa, specifically mentioning countries such as Germany, Ecuador, Hong Kong, Indonesia, Italy, Mexico, Thailand and the United States.16

The brand maintains a visible retail presence in Southeast Asia. For example, its official Shopee shop in Indonesia lists numerous Goospery products and has accumulated tens of thousands of followers, indicating sustained consumer engagement in the region.17

Legal records clarify the relationship between Goospery and its parent company. The U.S. GOOSPERY trademark was filed in 2014 and registered in 2015, with Mercury Corporation Ltd. identified as the owner. The goods covered included mobile phone cases, protective films, chargers, earphones, straps and holders.18

The brand has also been registered in other jurisdictions. Canada’s trademark database shows GOOSPERY & Design registered to Mercury Corporation Ltd. in 2024, covering cases and other mobile accessories. Consequently, Mercury Corporation Ltd. serves as the corporate and manufacturing entity, while MERCURY and GOOSPERY function as distinct brand identities within its portfolio.

The relationship between the two names is integral to the brand’s structure. Mercury’s trade materials explicitly describe the company’s brands as “MERCURY/GOOSPERY”. The company’s Korean website also prominently features Goospery-related branding and identifies the legal business as Mercury Corporation.

Therefore, Goospery is accurately described as a South Korean mobile accessories brand operated by Mercury Corporation, rather than as an unrelated entity.

Goospery is generally not positioned in the ultra-premium category defined by extreme protection or luxury materials. Its historical positioning aligns more closely with mid-range or affordable-premium smartphone accessories, emphasising attractive designs, variety, practical features, broad device compatibility, reasonable pricing and everyday protection.

This positioning appeals to consumers seeking distinctive alternatives to basic transparent cases without the price point associated with luxury or highly specialised protective gear.

Several product names have become associated with the Goospery brand over time, including:

• Mercury Silicone Case
• Mercury Jelly Case
• Soft Feeling Jelly Case
• Blue Moon Diary
• Leather Flip Diary
• Viva View Cover
• Easy View Cover
• Focus View Cover
• Sonata View Cover
• I-Pocket Premium Bumper

These names illustrate the brand’s historical emphasis on combining phone protection with additional functionality and visual styling.

The Goospery product ecosystem has evolved alongside smartphone technology. Current online material emphasises magnetic phone cases, wallet covers and MagSafe-compatible accessories, suggesting a shift from the older flip and diary-case-heavy portfolio towards magnetic accessories and newer smartphone ecosystems.19

Simultaneously, Mercury’s Korean operation continues to sell a variety of mobile accessories under its broader brand ecosystem.20 The brand’s evolution can be characterised as a transition from flip cases, diary cases and jelly/silicone cases toward protective cases, magnetic cases, wallet cases and MagSafe-oriented accessories.

Goospery’s primary differentiator has historically been design and practicality rather than extreme specialisation. The brand has benefited from long experience in smartphone accessories, Korean corporate and manufacturing heritage, broad compatibility with major smartphone brands, a large variety of designs, multifunctional products and international distribution.21

A limitation is that quality can be product-line dependent. As a thin silicone or jelly case differs fundamentally from a multi-layer bumper case, the Goospery name alone does not guarantee a uniform level of protection across all products.

The name GOOSPERY is a distinctive coined term rather than a conventional English product category. Trademark records show both the plain GOOSPERY word mark and stylised M GOOSPERY branding associated with Mercury Corporation.22 The branding has generally been presented alongside a stylised “M” motif, reinforcing its connection with the Mercury corporate and product family.

Goospery is a South Korean smartphone accessories brand associated with Mercury Corporation Ltd. Its roots extend back to the early smartphone accessory market, with trademark evidence showing commercial use from at least 2012–2013. The brand became particularly recognisable for smartphone cases, especially jelly and silicone cases, diary cases, flip covers, wallet cases and multifunctional protective cases.23

Rather than functioning solely as a reseller, Goospery has historically been tied to a Korean manufacturer with its own product development and manufacturing operations. Mercury’s historical materials claimed substantial export activity and distribution across more than 60 countries.24

Today, the brand continues to operate in the mobile accessories market, with its product emphasis expanding toward magnetic cases, wallet cases and MagSafe-style accessories alongside traditional protective case products.25
