Better quality and even better price
Size: One Size, Color: Cognac (Hundson)
The Timberland leather wallet has a classic look and feels high quality. The leather is soft but sturdy and breaks in nicely with use. It has plenty of card slots and room for cash without being too bulky. The stitching feels durable and built to last. Best of all, the price here was more affordable than buying directly from Timberland, making it an even better value.

Great high quality wallet
Size: One Size, Color: Black/Brown
Great wallet! Gifted to my boyfriend and he loves it. It has a nice leather and looks fantastic. It took some time like any leather to stretch out and fold nicer. Once worn into it has a nice slim fit! Only complaint is there is one spot you can’t put a card because it won’t fold.

Trifold style is perfect.
Size: One Size, Color: Black/Brown
Great style with the half fold and loved the inner section. Very stylish and many color choices. The negative is the material is very stiff. Not a soft leather. Maybe it will break in eventually.

I love the sleek design and how well it holds all my cards and id’s. It’s not bulky after either. The material also feels and look very durable.
