Parents can disassemble the inner Tritan plastic straw by removing the lid. LEAK RESISTANT SILICONE STRAW: Built for toddlers ages 2-3 transitioning from a sippy cup, the silicone straw and relief valve have built-in flaps that limit leaks and spills - great for daycare, car seats, and the dinner table. SEE-THROUGH TRITAN PLASTIC LID: The clear lid lets parents see exactly what's inside this 12oz toddler cup at a glance, so you always know how much water, milk, or juice your little one has had - no twisting, shaking, or guessing required. SOFT SILICONE STRAW & PROTECTIVE LID EDGES: A soft silicone mouthpiece is gentle on growing teeth and gums for toddlers transitioning from a sippy cup, while the soft co-molded border helps protect against dents when this toddler cup gets dropped. DISHWASHER SAFE & EASY TO CLEAN: Remove the lid and pull out the inner plastic straw for a deep clean - every part of this toddler water bottle is dishwasher safe, making cleanup quick and worry-free for busy parents.
