A Clean, Classic Fastener for Crafted Woodwork

The domed silhouette and zinc sheen bring a refined, utilitarian elegance to cabinetry, benches, and custom storage. I love the square-neck detail—it bites into wood for a smooth, unbroken face that feels tailored. Pair with pale oak and matte black brackets for a modern workshop aesthetic. Essential hardware that quietly elevates everyday builds to luxe, thoughtful design.

Nice and thin
Color: Black Tonal
Slim wallet. Made for a minimalist type of person. Ideally for only about five cards and some cash anything more the wallet will start to bulge.

Minimal and Magnificent
Color: Black Tonal
I've had more than a few front pocket wallets, and this one is up at the top. It's sturdy even though it's thin, and the stitching is even. Card retention is great with room for 1-2 cards per pocket, as well as room for a few bills to fit comfortably in the middle pocket. Probably going to buy another as a backup.

Perfect size, style, and material
Color: Ivy Green/Chicory Coffee
I love the Charlie wallet, it’s so sleek, fits everything you need, looks good, and made out of the best material. The amount of pockets plus the center fold makes this a really hard product to beat

Great option for a slim wallet.
Color: Black Tonal
I love this wallet. i bought my fist one and it lasted for a decade before the seems finally got some wear. It will eventually wear out some chips because of how tightly i pack it, but that is on me for trying to fit extra cards in there. Its a perfect slim wallet.
