This a very well made leather wallet with an RFID blocking lining. When it is first opened you see an ID window on the left, and four card slots on the right. When you turn the ID slot side outward, there are 8 more card slots. There are slots under the center and right sections, and two bill or receipt holding slots behind them. The card slots are snug, and I cannot see them stretching out for many years, if ever.  That is why I replaced my last wallet.  These wallets are crafted to last.
