Since there are large individual differences in the amount and condition of menstrual blood, we cannot provide a general guide to the amount of water absorbed.
The inside of Rinenna's cloth napkins are made of bioguard material with antibacterial treatment, but please refrain from using the same napkin for a long time, as it is not good for hygiene.
There are three sizes available: light daily use, normal daily use, and night use, so please replace them as often as disposable napkins.
