- Excellent moisture absorption: a professional desiccant factory with 26 years in dehumidification. Our silicate desiccants use highly efficient adsorption material and can absorb moisture up to its weight in water vapour in very humid environments. - Vacuum individual packs: 2 g, 5 g, 10 g and 20 g silica gel are vacuum sealed in small bags of 5 pieces. Use as many as you need; the rest are individually sealed for longer storage cycles, more convenient than 100 packs in a single vacuum bag to avoid waste. - Reusable: charging without wrapping paper (silica gel only) — Microwave mode: 2 minutes to quickly activate silica gel packets and bake for 0.5 to 1.5 hours at 150-200F. Charging with wrapper paper — oven baking temperature unchanged and microwave mode: place on glass or ceramic container, 560W for about 3 minutes; direct heat on a glass plate, 210W for about 3-5 minutes. - Colour indicator: the beads’ colour serves as a reliable moisture indicator and alerts you to replacement when the beads change from orange to dark green. The desiccants are made from food-safe raw materials and are safe to use in any situation. - Dehumidifying companion in daily life: the silica beads are tested under strict food regulations and are very safe. Ideal for storing food and medicines as well as electronics, tools, 3D printer accessories, jewelry jars, nuts, snacks, biscuits, spices, animal food, seeds, candy, 3D filaments, safes, ammunition, glasses, jewelry, documents, camera lenses, clothes, shoes, cosmetics, books, bags, decorations, cameras, watches and many other valuables.
