Medela Ultra thin disposable nursing pads are particularly thin and discreet. They are ideal for use when small to medium amounts of breast milk are leaking. The nursing pads can help you feel protected and secure - discreetly. The innovative oval shape fits perfectly to your breast shape so that the lactating core can trap the excess milk. The soft, hypoallergenic liner has five absorbent layers, at less than 2mm thick overall. With a flexible leakage protector that prevents leakage from the sides.
