Thank you for viewing! This is a sponge-type dental floss. Wax, non-flavored, 40m, 10 pieces Package has been updated. 6 pieces: ¥1150 10 pieces: ¥1530 For those who don't like mint. It's a sponge type that expands when it gets wet, so it thoroughly removes dirt between teeth. You can also combine it with sponge floss, mint wax, and fluoride.
