Great quality
Size: One Size, Color: Black (Hundson)
Replacement. I bought the cognac one for my husband two years ago I am always doing laundry in a rush (laundry for 7, nonstop laundry mat in my home) I washed his wallet three times, yes cards and all! this wallet protected all of his items finally decided to replace it, poor man. I am making sure I do not wash this one!

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.
