Designed for use from 7 months, the 360 insulated tumbler (260ml/9 ounce) is a great way to help your little one transition from baby cups to grown-up cups. The unique 360 degree valve of our 360 insulated tumbler is lip-activated, so your toddler can drink easily from anywhere on the rim. In between sips, the valve remains closed to keep mess to a minimum. The removable valve separates into 4 distinct, easily cleaned parts. The 360 cup is a great alternative to straw and sippee cups and a useful tool in helping your little one develop grown-up drinking skills. As with all Tommee Tippee cups, the handles can be added and exchanged with other cups in the range, and at the end of the day everything is easy to clean, either in hot, soapy water or on the top shelf of the dishwasher.
