어금니 용 이라서 펀하게 써도 좋겠어요
Children have a hard time using dental floss, you know.
My child feels awkward wearing it on their finger and has trouble opening their mouth as wide as possible. I think this is good to use in those situations. You just place it against the teeth and squeeze shut; the upper teeth press down, causing the floss to slide right in, which the child finds fun.
A similar product made of 3M is also sold on 11st, so give it a try.
