An earth-friendly alternative to preserving breast milk without the use of plastic bags: This freezing system lets you divide milk into half-ounces so you won't need to thaw more than you need. High-quality, flexible silicone bottoms allow you to easily pop out cubes and put them into either wide or narrow-neck baby bottles. When you're through with your breastfeeding journey, keep enjoying your Milkstache for frozen baby foods or for your own fruit-infused cubes to make water a little more tasty. FSA, HSA and HRA reimbursable.
