Great for serving snacks, storing larger portions of baby food or even homemade playdough, these containers are super versatile. They're microwave safe, freezer safe and leakproof. And they stack vertically and attach horizontally. These pods grow with your children and can be used well beyond the purée phase. Make a fun snack container train by putting a different snack in each of the compartments, attach them in one long line and serve!
