It's four products in one convenient stackable unit! The five-tier stack can be used as a formula dispenser, a snack case, a serving bowl, and a pacifier holder. Patented secure click design prevents cap from falling, and separate containers keep contents from mixing. Each tier can hold up to 8 oz of infant powdered formula and approximately 1/3 cup of dried goods. Store, stack, and dispense powdered formula, infant cereal, snacks, pacifiers, feeding accessories, and more in one convenient unit with Packin' SMART®.
