Japanese company Gyoko has created a line of satchels and smartphone pouches that feature the same stitched plate style used in Samurai armor. This is a very cool thing.
The Samurai satchels and pouches are being sold through Gyoku, Wanokaze and Village Vanguard. Just keep in mind that they have proven quite popular, so quantities are limited (or nonexistent at this point). Some of these stores do ship internationally.
