This leak-proof straw cup is the perfect next step for children who are already learning to drink more independently. The slightly larger size makes it suitable for slightly longer drinking moments as children grow. The cheerful and user-friendly lid features an anti-leak design, which keeps the straw clean and prevents spillage when the cup is closed. Made from sturdy, odorless and transparent Tritan™ that does not break and is easy to clean. Of course also dishwasher safe, and designed for long-term daily use.
