Medela Washable Bra Pads are made from a special anti-microbial material which reduces the risk of odours and bacterial growth. These quality nursing pads have ultrasonically sealed stitching which prevents breastmilk from leaking out through the seams. The material is thin and breathable and this ensures your comfort. Reuse again and again. Wash the bra pads at 40° to 60°C.
