Featuring a stackable and interlocking design, our BEABA Baby Food Storage Clip Containers make storing & transporting babys meals easy. Store anything from purees to finger foods to dry snacks! Use the stack and lock feature for organizing daily meals, or grouping together meals for grandparents or babysitter when theyre watching your little one. These portions are 100% airtight thanks to the screw thread lid, which means theyll even hold liquids like breast milk, and you can slide them into the nursery bag with no risk of leakage. Store them in your fridge, freezer, or cabinet, and defrost and reheat (without the lid) in the microwave.
