2 sets A great storage bag that allows one person to easily store a futon and has dehumidifying, deodorizing, and anti-mite functions. Reference price: ¥6,200 Body: Non-woven fabric (with B-type silica gel) Approximately 140 x 200 cm Compatible sizes: Single, semi-double (only when the futon is folded in thirds vertically), double (only when the futon is folded in thirds vertically) This is a futon storage bag that uses non-woven fabric with B-type silica gel for the side fabric. Silica gel has moisture absorption and deodorizing properties (ammonia, acetic acid, isovaleric acid, nonenal), and also has an anti-mite effect because the silica gel dehumidifies. Fold your futon vertically and place it in the center of this product, fold the fabric on both sides inward, fold it in half or thirds, and secure it with the buckle, allowing one person to easily store the futon. * Compatible with single size. Semi-double and double sizes are also compatible if the futon is folded in thirds vertically. The size is designed to fit in a closet, and can be stored either vertically or horizontally to suit the space. With a moisture sensor, it indicates the timing for ventilation or sun-drying in the closet by changing from blue to pink. With a transparent window, it's convenient to check the contents at a glance without having to pull it out of the closet.
