A diaper bag, nursery or home must have to store, dispense and organize items. Get smart and get organized with our stacking, twistable, LEAK-PROOF containers. Each container can be securely stacked together until ready to use with our leak-proof twisting design. The removable inner lid makes dispensing easy and makes it harder to spill the entire contents. Each container holds approximately 1/2 cup of liquid or up to 5 scoops of powdered formula for a full 10 oz. feeding.
