Nice
I love it. It's a nice slim wallet. Nothing special, but looks really nice, works well. I've been using it for a month with no problems. It's nicely lined, seemingly well made, etc. I got a good price on it, so I'm happy.

Wonderfully made, but not well sized for US currency
This is a very nice slim billfold, but unfortunately, it's not well sized for US currency. Probably for Euros. US Dollars fit, but it's a touch too narrow across to easily insert a bill. So you'll have to very diligently straighten and align a greenback to make it fit.
