Genuine leather Japan leather Mostro back case AQUOS series

■Shell-Type Smartphone Case Compatible with All Models
We offer back covers compatible with almost all smartphones. Designed to fit each model, you can use the case with its convenient functions intact.

■MADE IN JAPAN Leather with Attention to Coloring
Made from vegetable-tanned Nume leather, featuring a rare pale pastel color for tannin-based leather. Each piece of genuine leather is carefully waxed by craftsmen by hand, allowing you to enjoy the authentic aging characteristic of genuine leather. "MOSTRO (-MOSTRO-)" means "monster" in Italian, named for its intense aging effect.

■Full Leather Finish
Using proprietary technology, the case is finished by covering from the back to the sides with a single piece of leather.

■Smooth Operation for Various Functions
Each model has camera holes and speaker holes, allowing you to perform various operations such as fingerprint recognition, volume adjustment, and charging while the case is on.
※ Some models cannot be operated with the case on.
※ Compatibility with desktop charging or wireless charging is unconfirmed.
※ Depending on the case arrival time, the volume and power buttons may be covered. You cannot choose, but rest assured that operation is not affected.

■Subtle Logo Engraving
The COVERARY brand logo is engraved on the lower back of the case. The small, understated engraving adds a visual accent.
※ Depending on arrival time, some cases may not have the brand logo on the back.

■Edge Color Matching the Leather Color
The edges of the cut surfaces are finished with resin coating (Koba coating), creating a sharp impression in a color matching the leather.

■Handcrafted by Artisans
From cutting, attaching the case and leather, edge coating, to the finishing engraving, everything is carefully handmade.

■Model-Specific Resin Case
The base polycarbonate case comes in two types: clear and black. You cannot choose due to stock status, but it fits perfectly for your model.
