Product Features of the Premium Square Case
Frame and Panel Separation Structure

The high-quality printing of the Premium Square Case is achieved through a unique separation structure of the frame and panel. Unlike conventional on-demand smartphone cases, which are typically surface-printed and have limitations in color reproduction, the Premium Square Case allows for printing on the reverse side of the panel. This maximizes the printer’s capabilities, resulting in a very high-quality finish.
Minimal Design with 3x MIL-Spec Impact Resistance

The Premium Square Case boasts exceptional impact resistance, achieving three times the MIL-spec standard. The frame and panel separation structure also helps to mitigate impact from drops. The case has successfully passed multiple drop tests from a height of 3.6 meters at various angles. This allows for a minimalist design while delivering superior protective performance.
Entirely Sustainable Materials

Both the frame and panel of the Premium Square Case are made from recycled materials. Furthermore, the designs are printed using Mimaki Engineering’s GREENGUARD Gold certified UV-curable ink, and all product packaging uses recycled paper. caseplay is committed to environmental initiatives across all aspects of its operations.
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 empirical scientific data, products with low chemical emissions into indoor spaces and greater environmental consideration receive certification. There are two types of certification: standard and Gold, with Gold having stricter criteria.
