Feeding your baby when you’re out and about is much easier with ZoLi On-the-Go. Each individual container keeps your formula or snacks fresh until you need it and the easy-pour spout transfers the contents into a bottle or cup easily without spills or mess. The easy stacking system lets you decide how many you want to take with you…1, 2, 3, or all 4. And the tall stacking format makes it easy to locate in your diaper bag.
