Good Product
Size: One Size, Color: Smooth Finish Black
Good product although the leather is a bit stiff. Hopefully it will soften up over time. Fair price, fast shipping…

So far happy.
Size: One Size, Color: Glossy Nappa Black
As everyone has made clear, it holds credit cards very tight. Almost 3 weeks in & mine seems to be breaking in a little, but cards are still a bit difficult to remove. No complaints with money clip.
One thing I thought was a dumb move on manufacturers part, was inside one of the card slots is a tag sewn into the seem. This makes things alot worse while trying to fit cards into all slots. The tag will catch on the cards & bunch up in the corner of the slot making things even tighter in that slot, plus all slots surrounding it.
I was able to get a scissors in there enough to cut most of the tag out, without cutting the stitching itself....it made a big difference....enough to fit an extra card in & without it bulging up the wallet overall.
Why would they feel it necessary to do this is beyond my pay grade. Its not like you can even see what the tag says until you cut it out.... I believe it was the name & logo....but Jesus, how unnecessary, & in the dumbest place one could possibly think of. Especially when EVERYONE comments on how excessively tight it is to fit cards in the slots & also be able to retrieve them with relative ease when needed.
Overall I am happy with this wallet so far.... I'll be interested to see if it holds together over the long haul or if the stitching gives out in a year & has to be replaced.
I will update this review as time progresses.
UPDATE: Its almost to March 27 2023 & its been holding up great. No ripping or tearing stitching holding strong.
Still holds cards really tight, but they are easier to remove.

Worth the money
I have tried other slim wallets but keep coming back to AlpineSwiss. Theirs are much better in construction and in material, and last extremely long. Much better than the cheaper alternatives. Consider paying a bit more but getting your moneys worth with these guys.
