Say goodbye to musty smells and damp cupboards. Prep Marathon Dehumidifier Refill Bag 350g pulls excess moisture from the air to help stop mould spots, condensation, and stale odours. It is simple, quiet, and requires no power.
No special container required
Use it with what you already have at home. Just pour a portion of the crystals into a small open container such as a ramekin, takeaway tub, or jar without the lid.
