I was nervous due to price drop about the quality of this product but it is truely a carhart item and packaged inside of a carhart tin with carhart tags. Item only shows one photo which was suspicious as well. I googled model # to see other views of item and what I received matches perfect. Very happy!

Very nice wallet

Size: One Size, Color: Black

Very nice wallet, but I’m curious why in one day it was a 1.62 cheaper and how do I match that price? This is a follow up to the above. I bought this wallet to replace a bifold, but I found that all the stuff in the bifold does not when put into this trifold does not allow me to close it and put it in my pocket. So as nice as this wallet is and it really smells leathery. I’m going to return it.

Works well, not too big, even when full of cards and cash.

Size: One Size, Color: Black

Great leather and nylon wallet. I already had this wallet from about 10 years ago and my old one just wore out - chiefly, the clear plastic in the center cracked and fell apart. The new one is made just as well as the old one was.
