Just like a single-use juice box, only it’s good for the planet. Fill up Drink in the Box with your child’s beverage of choice time and time again – they’ll love sipping through the pop-up straw (and you’ll love that it’s leak proof). Holds 250mls. Pack contains 24 units, 6 of each colour. Did you know you can buy replacement parts for this product? We know that sometimes, life happens. That's why we've made sure you can purchase a set of new straws and a cleaning brush or a replacement mouthpiece, seal and straws.
