Philips Avent ISIS Duckbill Valves 6 ea

"\"These valves are great improvement to the old ones. The old valves wear out within 4 weeks or so if used on a daily basis and when it does wear out it keeps on falling into the bottle that the precious milk has been expressed in. The new valves are great. I bought a pack about 1.5 years ago. I only used one valve so far and it is still to wear out. The Philips Avent ISIS Duckbill Valve has not fallen into the expressed milk. I love it. Awesome product"
