Abstract: The invention disclosed herein comprises a wallet, cardholder, billfold, purse, phone cover or enclosure, passport cover, identification card cover, backpack or other personal bag or container which includes a pocket created by forming an enclosure with three corners with an opening or slot sized as appropriate for the card, currency, papers or other documents as desired. The user inserts one end of the card into the slot and pushes the card into position whereby the three corners of the card are positioned in substantial alignment with the three corners of the pocket and retained in relative proximity. As one or more cards are inserted and removed from the pocket, the remaining cards are retained in the pocket by the resistance imparted by the three-corner structure of the pocket.
