Pump & Serve! Do you love Boon Nursh bottles? (Of course you do!) The Boon Nursh pump adapter for wide neck bottles lets you easily pump directly into Boon Nursh bottles from your spectra or Avent breast pump to prevent the loss of precious milk due to messy transfers. This also means the bottle will already be ready when your little one is craving the good stuff at mealtime. This adapter set includes two pump adapters that are compatible with Avent Manual and Single/Double Electric Comfort models as well as with Spectra S1, Spectra S2, and Spectra 9 plus models. The adapter attaches securely to the pump flange and Nursh bottle for a direct transfer - so that you can be sure you're not wasting a drop of the good stuff. This set of pump adapters is made without BPA or PVC, with a dishwasher-safe design that ensures baby's favorite bottles are ready for mealtime.
