This is a silica gel dehumidifier that effectively absorbs moisture. The size is approximately 10 x 18 cm, a large size. The weight is around 250g per piece, with some individual variation. Two pieces are packaged in one bag, and we sell a set of two bags (4 pieces). This product is a remanufactured item, repackaged after being used once. There is no problem with its use, but we do not recommend it for food use. It can be used for dehumidifying shoe racks, closets, and for making dried flowers as a hobby.
