For generations, children have used Mepal’s Campus school products for their food and drinks. The pop-up bottle features an airtight seal so that no liquid leaks into the school bag. Press the button on the side of the lid and the bottle is ready to drink from. Then simply press the spout and the bottle closes tightly again. It comes in a multitude of bright and cheery colours and with many different cool and cute designs, for appeal to both girls and boys. ABS is a sturdy and impact-resistant material that has a polished and decorative surface. The product is dishwasher-safe, but cannot be used in the microwave or freezer.
