It has a stainless steel body with a 304 steel exterior and a 316 steel interior, paired with double-wall insulation to keep drinks at temperature for hours. A BPA-free silicone tip makes sipping gentler on gums and teeth, and the drinking hole is designed to let kids control the flow at their own pace.\u003c\/p\u003e\n\u003cp\u003eThe one-touch flip-top cap locks closed to help guard against leaks, and a carry strap lets kids tote the cup on their own. All parts, including the silicone tip, ring, and cap, are fully detachable for thorough cleaning and the cup is dishwasher safe. The exterior finish is electropolished rather than treated with polishing compounds, so no extra scrubbing is needed before regular washing with a neutral detergent.\u003c\/p\u003e\n\u003cp\u003eIt is not completely leak-proof, so it should be placed in a sealed bag or container for storage or transport.
