The Sunveno manual breast pump is great for mommies to express residual milk that the baby has not sucked during breast - feeding or for emptying the breast in case of milk residues. It can also help to collect the leakage while a mum is feeding from the other breast or expressing milk. This Breast Pump is designed anatomically that makes the pumping easy and comfortable. Comes with a cover lid to keep the expressed milk safe from spilling.
