Silicone Straw Covers for Stanley 30&40 Oz Tumbler

Our straw caps have a diameter of 10mm (0.4in) and are designed to be perfectly compatible with the Stanley 40 oz/30 oz tumbler with handle, and for the simple modern 40 oz tumbler with straw. They also fit all large-diameter long straws with a diameter of 9-11mm, but please confirm the size of your straw before purchasing the straw cover cap. Made of food grade silicone, these straw covers are durable, reusable, and easy to clean by hand or in the dishwasher. They're airtight and sealed, dustproof and splashproof, making them perfect for outdoor activities. Plus, they can help encourage children to drink more water. These straw toppers are not only stylish, but practical too. They effectively block dust and other foreign objects from entering your drink, without harming your body. **cup not included ** Smoke and Pet Free Home NWT
