Well made, high quality wallet
Size: One Size, Color: Brown
I bought this for my husband for Father's Day. It's a beautiful, well made, quality wallet. The stitching is heavy duty and the leather is very nice. It isn't bulky. A few months of having it and it seems to have broken in well.

Good wallet all around!
Size: One Size, Color: Brown
I needed a new wallet, it was here, its durable and going to last a while, it has everything I need it to. Theres two spots for where traditionally cash would go, which is nice, and a lot of spots for cards or IDs! Pretty safe, all I've lost is coins when it's upside down when I have too many so thats a good sign! It did have a 'new leather' smell when I got it, but it has gone away after a while, and it looks great! The leather feels and looks high quality! I didn't even know there were magnets, so I cant review them, woops.
