Tommee Tippee Explora Training Sippee Cup When you"re out and about the non­-spill valve prevents unwanted spills, and the big handles make it really easy to hold on to ­even one handed! At home, when a few dribbles don"t matter, it"s easy to remove the handles and non-­spill valve so they can hold the cup and practise free flow drinking, which can help their oral development. The soft spout on this cup is smooth and gentle on gums, even during periods of teething, and we"re also smooth and gentle on you: all our cups are dishwasher safe if placed on the top shelf and can be steam sterilised.
