Gelato Pique Baby Straw Mug This mug is recommended for carrying around as it is designed to prevent leaks even if shaken or tipped over, even with the lid open. The body weighs approximately 93g, making it easy for children to hold. In addition, all parts are dishwasher and boil-sterilizer safe. Some parts are also compatible with chemical and microwave sterilization. The bottle uses a clear material for easy viewing of the contents. It has a scale, so you can see how much your child has drunk. It also has handles on both sides, designed to be easy for small children to hold. Unused, but the box is slightly dented. Shipping will be via Yamato Takkyubin (Yamato Transport).
