NOTICE: If safe contents are already damp, these small desiccant packs will quickly become saturated. Safe contents must first be dry before you use these. It is suggested that you first dry safe contents outside of safe or purchase larger sized desiccant packs for initial drying.

These desiccant packs are ideal for home and office safes to knock down humidity. After depletion they may be reactivated by heating in an oven. These are Food/Pharmaceutical grade so you can be confident they won't damage the contents of your safe.

Desiccants are packaged in "Units" sometimes abbreviated by the letter "U". A Unit of desiccant refers to its drying capacity, not its volume. A Unit (approximately one ounce) is the amount of desiccant that will absorb at least three grams of water vapor at 20% relative humidity and at least six grams of water vapor at 40% relative humidity at 77 degrees F. Each of the packs in this item contain 1 Unit of desiccant.
