ZoLi BOT 9 Ounce | Weighted Straw Sippy Cup, BPA Free, Green
This sippy cup isn't your ordinary one. The BOT Sippy Cups features the original SILIFLEX-straw technology that is designed with a weighted ball so the straw always moves to the liquid regardless of the orientation of the cup. With its valve-free flexible straw, weighted ball and integrated handle, both babies and toddlers will find it easy to sip to the last drop.
