"Moon Pants Heavy & Night" has an absorbent sheet up to the waist so that you can rest assured even when sleeping, and it is designed for many days and nights. Like daytime, it has a smooth fit. The thin cloth does not feel oppressive, but it protects the waist firmly, so you can rest with peace of mind without worrying about staining the sheets. The crotch is also deep, so it is recommended not only for night but also for heavy days and days when you have to sit for long meetings. The cloth on the crotch part prevents the growth of bacteria by a semi-permanent antibacterial action with a patent, and there is no smell or stuffiness. Since it is not a disposable sanitary product, it does not produce garbage, and it is safe for the environment and economically. In general, the amount of menstrual blood on a high day (day 2) is 30 ml. "Moon Pants Heavy & Night" absorbs water from 3~4 napkins (15~20ml), so it can be used by those who have problems with urine leakage. On many days, we recommend using it in combination with tampons, menstrual cups/discs, or changing moon pants. * Do not put it in the dryer * Do not wash at high temperatures. * Please put it in the net and wash it. * Please do not pull strongly. * The design of the package is subject to change without notice.
