Chiyaki × COVERARY Genuine Leather Colorful Collaboration Back Case

A collaboration smartphone case with illustrator Chiyaki has come true!

With the theme "Feelings toward people connected through smartphones," the smartphone case was designed to be easy to hold, imagining an item that Chiyaki herself would want to actually use.

Expressing Chiyaki's worldview in print on a canvas of high-quality leather.
We luxuriously use leather with a textured grain that resists scratches, also used in luxury bags and high-end shoes (01_Pink, 02_Purple, 03_Blue), and Japanese-made leather with a popular metallic finish for leather goods materials (04_Silver).
