The Play Tumbler is designed for kids’ play. The tumbler holds 300ml / 10.2oz. The straw-type spout feels comfortable on the mouth and is easy to sip from. You can also detach the straw inside to drink. Vacuum insulated, it retains the temperature of cold drinks for a long time. It comes with a handle, and there is a slight curve between the lid and tumbler which allows small hands to grip easily.
