Straw cups are great alternatives to sippy cups, with a soft straw helping to develop sipping skills. The soft, silicone straw is easy to drink through and little ones don't have to tip the cup up very far to drink from it. Featuring INTELLIVALVE™, a unique anti-leak technology which guarantees this weighted straw trainer cup is completely leak-proof as it withstands internal pressure meaning the cup won't leak even when it is turned upside down or shaken. All our products are BPA, BPS, PVC, Phthalate and Nitrosamine free.
