I've made a key holder using approximately 2.8mm cowhide leather cord. In the image, it's attached to a wallet and used as a handle, but you can use it freely on bags, smartphones, etc. The hardware used is a seamless O-ring, so please connect it using a carabiner or similar. See image ①. If you wish, I can include the round carabiner shown in image ④. Please let me know when you purchase. The leather is the same type used for glove lacing, so it's thick and quite durable. It will develop a shine with use. ◎ Hardware: Seamless O-ring ◎ Total length: Approximately 19cm If you have any questions, please ask. #leather #leathercraft #leather #genuineleather #numeleather #tochigileather #himejileather #tatsunoleather #americancasual #leatherwallet #walletchain #calee #Calee #HTC
