As with most Tush products the Tush card case is entirely hand made by the man himself, in Yokohama. The finest quality thick, Japanese leather is cut by hand, stitched by hand, and detailed by hand, no machine process whatsoever. If you're in the market for an artisan made, leather card case then you should look at one where the artisan in question is the only machine involved.
The treatment of leather can depend on the type of leather, and the colour or patina which you wish to achieve with wear. Natural hides can become dry over time so we recommend an occasional, as desired, treatment with a quality leather preservation product or conditioner. Our personal usage has lead us to trust products such as Huberds boot grease, Obernaufs LP and Mustang Paste.
