The 24mm diameter Neno silicone breast pump funnel is suitable for 19/20/21mm diameter nipples, which is the most universal. This is a replaceable part of the breast pump, which is placed on the breast to express milk, and one of the reasons for its replacement may be the change in the shape of the nipple during breastfeeding. Even a small change can affect the comfort of using the breast pump, and the correct adjustment of the overlap is very important.

When expressing milk with a breast pump, the nipple should be free in the funnel. It should not be too loose as it can cause the areola to tighten. However, a funnel that is too small can cause discomfort, clogging of the milk ducts and irritation. The correctly adjusted size of the Neno overlay ensures comfortable use of the breast pump. The soft silicone from which it is made adapts to every breast, regardless of size.
