Disposable sanitary box (bags) 27 bags. Purchased a box of 30 for 1580 yen, but my daughters are sisters, and sometimes their periods overlap. The traditional sanitary box suits us better, so I'm selling these. The bags are sturdier than those from 100-yen shops, and I feel they have better odor resistance. I think it's a very convenient product because you don't need to place a sanitary box.
