Description: With the Willow portable breast milk cooler you can store up to 16 oz of breast milk at a safe temperature for up to 24 hours. Our insulated cooler features a gel ice pack that remains separate from milk to prevent potential contamination and is TSA compliant! A top loop handle for easy carrying, it's the portable breast milk chiller you'll bring everywhere. Used only handful times. I nursed so didn’t use it. Keeps milk cool for 24h, and can be used for all other drinks for hot summer! Size: 16oz Originally $40 + tax.
