Set of 2 Protective Shells + 2 Collector Shells by Suavinex. The collector shells, without colour or holes, can be used as a breast milk collector to collect milk loss during breastfeeding. Designed to be coloured on the opposite breast when breastfeeding or when expressing milk with a breast pump. Also very useful for mothers with excess milk. With a small notch at the top for easy emptying. The coloured protective shells with holes are the perfect help when nipple irritation or cracking occurs, as they prevent clothing from rubbing against this sensitive area. The ventilation holes also allow the breast to be well ventilated, making it easier to heal, and the shells are super-discreet when placed inside the bra. The soft, flexible silicone pad sits snugly against the breast without being uncomfortable. It is easy to put on and take off and is compatible with either type of shell (protective or collector).
