Philips AventTwin Expression Kit

The gentle-draw vacuum mimics baby's suckling to create a steady milk flow that requires less pumping.

Five soft petal massagers gently flex in and out, working in tandem with the reliable vacuum. This is intended to help stimulate a fast, natural milk flow.

This Twin expression kit's funnels are only compatible with the Twin electric breast pump, due to different valves and a closed diaphragm. The Twin expression kit will not fit the manual or single electric breast pump
