This is a must have for all your period undies - makes washing them so easy. We recommend keeping in the bathroom for girls to simply rinse their underwear either whilst in the shower or in the hand basin after use, then simply pop into the washbag each time (can hold up to 5 pairs) then when full pop it into the washing machine ready for a load. Please remember no fabric softener.. Perfect also to wash all your bras and bralettes as stops them getting hooked on other garments.
