I had a tri-fold Big Skinny that began to wear out after 4 years. Not bad! I was happy with it the whole time until it began spitting out cards occasionally as the corners of the pockets collapsed and stopped holding. Also in the first year of the Tri-Fold, the thin liner in the cash pocket broke down and shed little pieces of rubber into my pockets, which wasn't great, but I still preferred it over a normal leather wallet.
I just bought the Curve bi-fold a couple of weeks ago, and it's good quality and feels comfortable to use. However, it is not very "skinny" and about the same size as a normal wallet when loaded with 13 cards and a few bills. I'll use it, hopefully for years, but it's not what I expected.
Merchant Response:Dear Randall, Thank you for your feedback. You might like to try our nylon World Wallet--the pockets are layered and the wallet is slightly taller allowing for a thinner overall profile. At your earliest convenience, please contact our customer service team at firstname.lastname@example.org or 617.500.6939 and they'll be happy to work with you on finding a style that better suits your needs. Thank you again for your review! Have a great day! BigSkinny
