■ Slim Protection Premium Case: 5,980 yen (tax included)
① Separate Frame and Panel Structure
The highest quality print of the Slim Protection Premium Case is achieved through its unique separate structure. Currently, on-demand smartphone cases on the market are typically surface-printed due to printer characteristics, which limits color vibrancy. By separating the frame and panel, the Slim Protection Premium Case allows for reverse printing on the panel, maximizing printer capabilities and achieving an exceptionally high-quality finish.
② Minimalist Design with 3x MIL-Spec Shock Resistance
The Slim Protection Premium Case boasts outstanding shock resistance, three times that of MIL-spec standards. The separate frame and panel structure also helps mitigate impact from drops, having successfully passed multiple drop tests from 3.6m at various angles. It achieves excellent shock resistance while maintaining a minimalist design.
③ All Sustainable Materials
Both the frame and panel of the Slim Protection Premium Case body are made from recycled materials. Furthermore, caseplay implements environmentally friendly initiatives in all aspects, such as using 'GREENGUARD Gold' certified UV-curable ink from Mimaki Engineering Co., Ltd. for design printing, and utilizing entirely recycled paper for product packaging.
*GREENGUARD is an environmental certification program for chemical emissions in indoor spaces, conducted by UL, a third-party safety science organization in the United States. Based on fair, empirically supported scientific data, products with low chemical emissions into indoor spaces and greater environmental consideration can receive certification.
There are two types of certification: standard and Gold, with Gold having stricter criteria than the standard.
