Designed specifically for trading card games and collectible cards with a 65% RH humidity level. Use Foil Armor ® 2-way humidity control packs to control moisture in an enclosed area. Our patented technology will either release or absorb moisture, maintaining relative humidity at 65% in a contained environment.

We include a smart, simple-to-read Replacement Indicator Card with our Foil Armor ® packs. Simply replace the old pack with a fresh one when the dot on the Replacement Indicator Card turns bright blue.
