Not sure if the brand is a biggy but the wallet it great.
I'd put up Mulholland Brothers up against just about any make in the leather department. Their styling leans towards the rustic, which I like, and the quality is tops. Anyone else like them?? It seems they are mostly known in California, as they are based in San Francisco. Mulholland Brothers
As for wallets, I really need a new (and a good) one. I use a very simple and slim bi-fold credit card case with a money clip attached to the side. I think it's by Fossil. I actually really like it - there are a lot of bad versions of that design, but this one works really well. Unfortunately the money clip recently stopped working. Anyone seen the "April in Paris" line of men's leather goods at Wilkes Bashford? Incredible stuff. The maker, Beatrice, was trained by and worked for Hermes. You can order bespoke goods at her Clement Street Botique. Highly recommended. April In Paris
