Love BoonÃ¢â‚¬â„¢s NURSH bottles? (of course you do!) The Boon NURSHÃ‚ ® Pump Adapter for Wide Neck Bottles lets you easily pump directly into NURSH bottles from your Spectra or Avent breast pump to prevent the loss of precious milk due to transfers. This also means the bottle will already be ready when your little one is craving the good stuff. This adapter set includes two pump adapters that are compatible with Avent Manual, Single/Double Electric Comfort models as well as with Spectra S1, S2, and 9 Plus models. The adapter attaches securely to the pump flange and NURSH bottle for a direct transfer Ã¢â‚¬â€œ so that you can be sure youÃ¢â‚¬â„¢re not wasting a drop of the good stuff.
