Mila's Keeper Breast Milk Storage Bottles are made of 100% Borosilicate Glass which is a premium-grade glass used in medical and laboratory settings. Unlike other glass bottles like mason jars, made of inexpensive soda-lime glass, our bottles are also thermal shock resistant which means that it can be placed safely in the freezer and bottle warmers.
Our glass storage bottles include sleeves and a lid made of 100% LFGB Platinum-Grade silicone. Silicone is an organic based polymer, which is non-toxic and unlike plastic it is very durable, easy to clean and odorless. It is soft, silky and will not stain when washed after each use.
Mila's Keeper prides itself in using the highest quality materials and full transparency. All components of our products have been tested and exceed all US FDA and CPSC tests for lead, cadmium, Bisphenol A, and phthalates all resulting in "ND" - or non-detected for the following tests and can be found below or here.
