This is a set of Japanese clothing and costume mats made from bamboo charcoal material, which provides deodorizing and antibacterial effects. There are 3 sets available. The yellow cloth is for wrapping the costumes, and the blue cloth is a bamboo charcoal sheet that has deodorizing, moisture-proof, antibacterial, insect-repellent, and anti-corrosion effects. Using them together provides a high level of effectiveness. Thank you for looking.
