Moisture Trap Refill Crystals, able to absorb up to 1 litre of water to help combat condensation. The crystals cause condensation to filter through into the container area below so can be emptied multiple times until the crystal are used up.

Used as a refill pack for our Damp Kontrol Moisture Traps (Link Here), we also sell larger 2.5kg bags (link here).

Crystals are an irritant and must be kept out of reach of children and pets.
