Product Lineup
Slim Protection Premium Case / Premium Square Case: from ¥5,980 (tax included)
① Separate frame and panel structure
These cases use a proprietary separation structure that enables back-surface printing on the panel. Compared to conventional on-demand phone cases, which rely on front-surface printing with limited color vibrancy, this approach allows the printer to operate at full capacity, delivering a noticeably higher-quality finish.
② Slim yet highly impact-resistant
The Slim Protection Premium Case offers 3× MIL-SPEC impact resistance, and has passed multiple drop tests from 3.6 meters at various angles. The Premium Square Case features uniformly thick corners and frame to absorb and distribute shock from all sides.
③ Fully sustainable materials
Both the frame and panel are made from recycled materials. The print uses UV-cured ink with GREENGUARD Gold certification from Mimaki Engineering, and all packaging uses recycled paper throughout.
GREENGUARD is an environmental certification program operated by UL, an independent safety science organization in the United States, assessing chemical emissions in indoor spaces. Gold certification applies stricter emission criteria than standard certification.
④ Magnetic ring compatible models available
Compatible with caseplay's Premium Card Wallet and Premium Ring Stand for added convenience.
