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. This PURE Pristine cup brings a fully 18-8 stainless steel build, double-wall vacuum insulation with a thermal copper lining, and our patented SiSA™ antimicrobial coating. SiSA™ uses the natural antimicrobial properties of silver — not chemical additives — to eliminate 99% of microbes on the drinkware's surface. The twist-on lid is splash-proof and leak-proof (because we know how this goes), with a BPA-free flip straw built for noisy slurps. Keeps drinks cold for up to 24 hours, and the cushioned, non-slip base survives every car ride, classroom snack, and toddler tantrum.
