Mila's Keeper Glass Breast Milk Storage Bottles come in two (2) sizes, standard and wide neck*, to accommodate different size pumps and nipples. Make sure you know which neck size is the right storage bottle for you.
*Spectra, Motif Luna and Maymom flanges: Due to temporary changes with the threading of our bottles, these flanges may be a little loose on a small percentage of our bottles. Therefore we recommend one of the following:
1) Purchase the wide necks and if they are loose, purchase these silicone seals from Maymom which secure the flanges.
2) Purchase the standard neck bottles and use with a wide converter for standard bottles, such as the adapter by Spectra, Motif, or Maymom.
** Evenflo wide bottles have recently changed their threading - see here. Our bottles fit the threading of the current nipple cap ring, not the new. Please check before purchase or use a compatible cap ring with their nipples.
The wide mouth of this size also accommodates milk poured from wearable, hands-free breast pumps such as Freemie, MomCozy, Elvie, and Babyation.
