Features a specially designed removable non-spill valve which helps reduce spills and can be removed when not required. The durable translucent tumbler has moulded measurement markings to allow you to check how much your baby is drinking. The spout lid is made of Flexisoft so it is gentle on gums and shaped especially for little mouths. Flexisoft is also featured on the sides and base of the tumbler for extra grip while holding. The Trainer Cup includes a spout cover which clips neatly onto the spout for hygienic travel.
