Thank you for viewing my products from among many others (*´∇｀*) This is a handmade cloth menstrual pad * fully breathable waterproof & absorbent liner. * Structure * From the skin side... cotton linen (80% linen) + flannel x 2 sheets + pile fabric 2 sheets + breathable waterproof cloth + cotton fabric Size... Length 22cm Width 17cm Snap... Plastic snap This is a total of 7 layers. * The absorbent material is sewn in the center. * Breathable waterproof cloth... It allows air to pass through but not liquids, making it a breathable waterproof cloth menstrual pad. We use the same waterproof fabric as cloth menstrual pad specialty stores♪ * This is the price for a set of 4. ⭐︎Fabric⭐︎ * Cotton linen (80% linen)... The linen content is 80% and also contains 20% cotton, so it has the coolness of linen but also a warm feel, making it a smooth fabric♪ The fabric itself is also very soft. The color is black. * Please wash once before use. This is, after all, a handmade item by an amateur. I make them with all my heart, but I apologize for any curved seams or frayed fabric. Please purchase only if you understand.♪
