[Uses] To remove moisture from your duvet during storage. Standard Dehumidification (water conversion): Approximately 4.2 oz (120 g) per sheet (when temperature at 25 degrees and humidity 80 percent). Usage Period: 1 to 4 months (depending on the conditions of the same usage place) may vary in seasonal and humid conditions. Be sure to replace it with new products within 1 year of the start of use. Ingredients: Calcium chloride, water retention agent (natural ingredients), mold and dust mites repellent (wasabi-derived ingredients). How to use: Remove this product from the outer bag, then place the moisture absorbing surface (white surface) on top, and then scissors one sheet on the folded futon. When the entire chemical becomes jelly, please replace it with a new "Dry & Dry Up" futon storage." When used in an environment with a high airtight seal, it will be more effective. When you open the outer bag, the moisture absorption begins, so please use it all at once (4 sheets of 2 duvets) Usage Standards: 2 sheets per duvet folded into 3 pieces. Caution: Do not take out the chemicals inside. In order to prevent liquid from spilling, do not scratch the chemical bag, oil (leather cream, etc.) or detergents, etc. If the liquid gets dripped, it may stain the futon.

If you put the chemical into your mouth, clean the mouth with water and drink 1-2 cups of water. If it gets into the skin or eyes, immediately rinse with a large amount of water. In any case, consult a physician. If the chemical adheres to your comforter, clothing, or metal, rinse thoroughly with water. If it cannot be washed, simply wipe it off with a water wipe and wipe back until it runs out of stickiness. Depending on the humidity of the place you use it, liquid may temporarily accumulate or agent harden, but it does not affect the effectiveness and quality of the product. Do not use for anything other than its intended purpose.
