Keep the exposed tip of a compatible reusable straw covered when it is not being used with this Silicone Straw Cover. Designed to fit selected tumbler and cup straws depending on diameter, the small cap can help reduce direct contact between the straw opening and ordinary dust or surrounding surfaces. Push the cover gently onto a compatible straw without forcing it and remove it before drinking. Exact internal diameter, silicone composition, shape, decorative design, colors, attachment loop and included quantity vary by model. Measure the straw diameter before purchase because one cover may not fit every straw size. Verify food-contact suitability before making specific food-grade or BPA-free claims. Wash before first use and clean regularly, particularly around small openings and decorative sections where residue can collect. A straw cover helps keep the tip covered but does not sterilize the straw or make an exposed beverage hygienically sealed. Small silicone accessories can present a choking hazard, so keep them away from babies and young children and inspect regularly for tears or detached decorative parts.
