10pcs Bouchons de Biberons Étroits pour Dr Brown et Medela Biberons, Sans BPA Remplacement des Bouchons de Biberons Voyage et Stockage avec Joint d'Étanchéité pour Ameda Biberons (Vert)

Perfect fit for Dr. Browns Glass Bottles (narrow bottle). Haven’t noticed any leaking - great for travel.I pump at night directly into the Dr. Browns bottles (using a spectra pump **with an adaptor piece on the bottle**) then store with these caps. Has made life so much easier not having to transfer milk into a different bottle and clean 10,000 extra parts. Quality has been great and love that it comes with so many. Much more cost effective than the white tops sold by Dr brown.After reading other reviews I was nervous that some pieces would be missing the inner ring to ensure an adequate seal, so I double checked when I first received the product and they all had them.

These fit all kids of bottles (not wide ones) and they are pretty leak proof too. They are easy to store I have a huge Tupperware container I use for all my lids and they don’t take much more space than normal. Also have multiple saves me washing and time.

Great fit and seal, we use for pre-portioning formula in bottles for overnight feeding.Easy to screw on and off, good thick plastic and durable through dishwasher.

These fit well for Dr. brown’s bottles. I used them for the glass ones and they worked well.

These caps are really handy for using Dr Browns and Evenflo narrow neck bottles. I primarily use these bottles for storage but the caps would be great for traveling, too. I find that I need to double check they’re tightened down since the rubber seal is quite thick. The seal prevents all leaks but make sure it’s seated correctly. They’re easy to rinse and wash and have held up well in my steam sanitizer bag.
