Ever 3-5 years, I replace my very worn wallet. It is always stuffed with ID's and credit cards. I prefer ones with 'windows" to flash the most frequent ID without pulling it out again and again. The billfold pocket is filled with miscellaneous receipts. In this context, the fact that there are two bill sections allows me to separate cash from receipts and the 11 card slots are more than I need. And it still maintains a very low profile. Stitching appears very solid.
