Why not eliminate a step and pump directly into your storage bag? The Honeysuckle® Breast Pump Bag connected to the Adapter makes it easy. Simply slip the notches in the bag over the hooks on the adapter. The other end of the adapter fits most breast pumps. No spills. No mess. No bottles to wash. Our bags come pre-sterilized and meet the highest standards in breastmilk storage. They are virtually leakproof, recyclable, oxo-biodegradable, BPA-free, and tamper-evident. A handy zip pouch allows one at a time dispensing. Honeysuckle Breastmilk Bags are currently being used by hospitals and milk banks in the Philippines! These include St. Luke's Medical Center, Makati Medical Center, Asian Hospital & Medical Center, and Manila Doctors Hospital. While no storage bag is 100% leakproof, Honeysuckle's industry-leading design and strict quality control ensure you of a virtually leakproof experience, bag after bag after bag.
