The NUK Kiddy Cup toddler cup features cute and colourful designs and is ideal for kids that love to get their teeth into everything. It is great for little teeth as the toughened spout withstands bite marks. It also glows in the dark for up to 8 hours, making it easy to find at night by simply placing it under a lamp or in the sun to recharge. The cup has a contoured shape for grasping and holding, and a leak-proof valve for easy drinking without pause and fewer messy clean-ups. Additionally, the flexible cap connection ensures the lid won't get lost, and a clip attaches to your little one's clothing, backpack, lunch bag, and more.
