New TI card wallets?

[John Garza (3665)]

Has anyone else noticed that TI cards degrade in their original wallets? TI-59 mag cards are the least affected, TI-58/59 plastic label cards become gummy on the printed surface until it sloughs away. SR-52 cards get blurry lettering and a pink background (instead of white). I have had some luck with adhesive remover and a mild warm soap bath. I have all my cards in paper coin envelopes now, but it's not a very usable situation. Anyone know of a replacement card wallet that will not deteriorate? It's a shame to spend all that effort to clean the gummy wheel issues, only to have more goo come into the reader from the cards themselves! -J
