Straw cups are an excellent alternative to traditional sippy cups, helping toddlers develop proper sipping skills without needing to tip the cup too far. The soft silicone straw supports speech development by strengthening lip, cheek and tongue muscles. Featuring innovative INTELLIVALVE technology, the cup is completely leak- and shake-proof. The straw is also infused with BACSHIELD antibacterial silver-ion technology to help reduce bacteria, prevent odours and maintain hygiene. Made from safe, high-quality materials, the cup is free from BPA, BPS, PVC, phthalates and nitrosamines for complete peace of mind.
