8 Gram Size - 6 Pack - 65% RH 2-Way Humidity Control Packs For Trading Cards

Used exactly as instructed, I put 5 cards in an air tight container for three days with one of the packs and it did absolutely nothing. A waste of $20.

Doesnt really work in colder environments. It did after a week and a half make a difference but it will be a while yet before the cards can be considered flat.

Turns Crunchy Taco Shells into Flatbread. Works great
