How to use
After wearing, rinse your leakproof seamless thong in cold water to release fluids and prevent stains. For best care, hand wash or machine wash on cold using mild detergent, ideally inside a mesh laundry bag to protect its seamless stretch fabric. Skip bleach, softeners, and ironing, which can damage the absorbent gusset and elastic fibers. Hang dry only, air drying preserves elasticity, shape, and long-lasting performance of your thong.
