SPILL-PROOF FOR ACTIVE TODDLERS — BUILT FOR EVERYDAY ADVENTURES: Designed for confident straw drinkers 12+ months who are always on the move. The spill-proof +Cut straw and flip-top lid help prevent leaks when your little one carries, tips, drops, or tosses their cup. Built for busy toddlers—and the messes they leave behind. SAFE FROM THE INSIDE OUT — PREMIUM PPSU + SILICONE: Every part that touches your baby's drink is made from premium PPSU or food-grade silicone. No metal or microplastics in the drinking path—just thoughtfully selected materials designed for everyday feeding and drinking. EASY TO CLEAN — TOP-RACK DISHWASHER, MICROWAVE & STERILIZER SAFE: All parts fully disassemble for thorough cleaning. Top-rack dishwasher safe, microwave safe, and safe for boiling or steam sterilization. Durable PPSU and silicone are designed to withstand repeated cleaning and daily use. TWO STRAW STAGES — SAME SEAL, DIFFERENT BITE: Both stages share the same leak-proof cross-cut straw and flow rate — only the firmness differs. Stage 1 (6M+) is soft for new gums and first sips; Stage 2 (12M+) is firmer to resist biting. Move up to Stage 2 once your toddler starts chewing the straw — it resists biting to help prevent tears and leaks. 360° ROTATING HANDLES — EASY GRIP, EVERY LAST DROP: Soft handles rotate a full 360° to follow your baby's hands — no awkward wrist twisting. They tilt with the cup, so your little one can drink down to the very last drop. GROSMIMI's Flip Top Spill Proof Sippy Cup is designed for toddlers transitioning to drinking from a straw.
