Duralumin carved jacket for iPhone 13 Pro

Sophisticated, simple and unique design.

It is a work that is carefully handmade by carving one by one from a piece of solid duralumin.

The result is a design that feels just right in your hand.

The floating structure of this product lies between the iPhone itself and the strongest duralumin jacket, and does not come into contact with them.

Advanced machining technique with three-dimensional processing and carefully designed in details are reproduction of designer’s unwavering intention to guard your iPhone.

The material of the jacket is "Duralumin A2017" which is also used in aircraft.

Each piece is hand-polished to maximize the luster of the metal.

"Super Durarumi A2024", which is even stronger and has a beautiful shine, is also available.

Please choose either one.
