I bought a few ultra pro magnetic holders and am having an issue with the case not closing properly and leaving the card exposed around the sides, my card is 55pt so i naturally got a 55pt holder. When i noticed the gap i took out the card and put a standard size signature card in.. still has a gap! Are they meant to be like this? Im a smoker and get paranoid they'l get stained with smoke seeping in. Any experiences or advice to keep my cards good?
