These cups with straw for children aged from twelve months were developed specifically by a multidisciplinary team required to design a product which was both spill-proof and dentally friendly. The result is a series of colourful drinking cups with an hourglass form, optimally shaped for the hands of infants. The cap and the soft, palate-friendly drinking straw are so designed that, thanks to an innovative valve, they are absolutely leak-proof when inactive.
