What are people saying about the Leakproof Cotton Bikini – Soft, Sustainable Everyday Period Protection?
How to use
Wear the cotton bikini just like regular underwear on period days, light bladder leaks, or for everyday protection as a worry-free alternative to disposable liners. Choose from regular, heavy, or super absorbency to match your flow. After use, rinse the underwear in cold water to help prevent staining. Then, hand wash or machine wash on cold, ideally in a mesh laundry bag to protect the fabric. Use mild detergent but avoid fabric softener, bleach, or ironing to maintain its leakproof technology. Always hang dry to preserve the elastics and extend the life of the underwear.
