No thread. No glue. Just geometry doing all the work. A different approach to leathercraft inspired by a zipper.
I wanted to see how far geometry alone could go.
This phone case is made from 2.2 mm red vegetable-tanned leather with black-painted edges to emphasize the interlocking pattern created by the assembly itself.
There are no stitches and no glue holding the structure together—just a zipper-inspired locking geometry.
My design philosophy is simple:
A great design should achieve maximum impact with minimum effort.
This construction method isn't limited to phone cases. With the right type of leather, it's surprisingly strong and can be adapted to many different products.
I'd love to hear what other applications come to mind.
