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.

Office Wear
Size: 10.5, Color: Optic White/Optic White
Great shoes for a casual day at the office. I have to size a half size down for Cole Haan usually. Comfortable and looks great with any fit.
