PERFECT 65% HUMIDITY: Foil Armor humidity packs maintain a precise 65% relative humidity to prevent curling and warping in trading cards, especially foils and holographic cards that are highly sensitive to moisture changes.
SIZE GUIDE: The 8g pack is ideal for flattening up to 5 warped cards in 24 to 48 hours or preserving small collections long term. The 33g pack handles up to 10 cards or can maintain stable conditions in larger storage setups.
HUMIDITY INDICATOR: Each pack includes a color-changing indicator card that clearly shows when it's time to replace. Change the Foil Armor pack when the dot on the card turns bright blue.
SAFE FOR RARE CARDS: Made with only food-safe glycerin and water, contains no harsh chemicals. It’s a clean, safe, and reliable option for all types of trading cards, including rare and graded ones.
FLATTEN TRADING CARDS: Foil cards warp due to humidity imbalance between paper and foil layers. Low humidity causes inward curl, high causes outward curl. Foil Armor locks in stable RH to eliminate warping at the source.
