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 some recent inconsistencies with the threading of our wide necks, these flanges may or may not be secure with these brand pump flanges.  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 hereOur 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.

Volume: 5-6 ounces | 150 ml

Weight: Standard: 6.2 oz; Wide: 6.8 oz
