Our unique big kids' 600ml drink bottle is ideal for kindy and school kids. Its unique triangle shape bottle is designed specifically for little hands, making it easier for kids to grip. Better for school aged kids - this larger 600ml bottle is a little heavier than our 450ml bottle when full of liquid. Easy push button pops open the lid, keeping straw tops hygienic when closed and never goes astray. Spill-proof bite valve straw top prevents accidental spills. Robust carry handle makes it easy for kids to carry and remove out of school bags. Its 600ml capacity and angled silicone straw lets kids drink to the very last drop and stay hydrated throughout the day. Minimal parts and ultra easy to assemble / disassemble and clean. Dishwasher safe (top rack only).
