I had purchased a competitor's "vintage" holder for some 1955 Bowmans and there was too much space in the recess, allowing the card to shift around. After looking around, I found The Pennysleever and thought they would work better. Boy was I right! The recess fits the cards like a glove, the corner cutouts protect the card corners, the magnet is very strong, and the case itself looks clear and clean. I plan to pick up some more products from here when I need them.
