Avoid messy clean ups with the Click Lock Insulated Straw Cup from Munchkin. This clever cup has a simple click-and-lock lid which has been designed to be completely leak-proof when closed. Its contoured shape is easy for little hands to hold and a clear outer with colour tinted cup means you can see the fill level. The cup is also insulated to keep drinks cool and features a soft, flexible spill-proof straw. The Munchkin Click Lock Insulated Straw Cup is BPA free and is dishwasher safe when placed on the top rack.
