This is a prototype wallet that I just finished. The outside is black vegetable tanned horsehide (9oz) and the inside is a new chrome tanned horsehide leather I was trying out. The billfold is lined with brown cotton selvedge duck. As with most of my wallets I've added two vintage (1920's era) pure copper rivets. This give the wallet and extra two pockets in the back to hold extra cards or papers. Four built in card slots on the front. The new chrome horse is very soft and supple. More so then my normal veg tanned so this wallet is not near as stiff as my normal wallets. If you prefer a softer wallet, then this one might be for you. I took a pic of the wallet next to an iphone to give you an idea of the size. Since I was trying out the new leather this wallet is sold as a prototype so the price is much lower than normal. Selling it for $50.00 + shipping. PM me or email me at [email protected] if interested.
