Big-cup energy for tiny humans. The Twistie Kids Cup is a 14oz insulated stainless steel tumbler scaled for small hands but built like the grown-up version — twist-on, spill-proof, leak-proof lid (because we know how this goes) and a BPA-free flip straw built for noisy slurps. Antimicrobial SiSA™ coating keeps germs in check, double-wall vacuum insulation keeps drinks cold for up to 24 hours, and the cushioned, non-slip base survives every car ride, classroom snack, and toddler tantrum. The training-wheels tumbler that earns its keep.
