Misleading
Size: Small, Color: Brown
This is a very horrible material and poorly made suit, I have never bought anything this bad in amazon before, the crazy thing is that I returned this thing to get a refund and they shipped back the exact same garbage back to me.
I clearly do not like anything about it, this is a misleading advert

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.
