The YOUCOX Adjustable Straw Cover is a groundbreaking innovation designed to address the common issue of fixed-size silicone covers not fitting various straw sizes. With each brand's tumblers and cups featuring unique straw dimensions, the cover you previously purchased may not be suitable for your particular straw. To solve this problem, our team developed this adjustable straw cover that can accommodate straw diameters ranging from 6mm to 10mm, regardless of the brand.

This is the only adjustable straw cover of its kind available on the Amazon market, and any other products claiming similar functionality are counterfeit. The YOUCOX Adjustable Straw Cover is compatible with a wide range of popular tumbler brands, including Stanley, Simple Modern, Yeti, Owala, Hydro Flask, Reduce, Maars, Meoky, MaxBase, Beast, Hydrapeak, and many more.

Crafted from food-grade silicone material, this cover is BPA-free, durable, and non-toxic, making it safe for daily use. It is also reusable, dishwasher-safe, and suitable for outdoor activities, as it provides a dust-proof and splash-proof seal to keep your straw and cup hygienically clean.

Whether you own a Stanley, Beonsky, HIWARE, Ajedrmy, VITEVER, or any other tumbler brand, this adjustable straw cover will seamlessly fit your straw, solving the common problem of size incompatibility. The innovative design with an adjustable internal diameter of 6mm to 10mm ensures a secure and personalized fit for all your straw needs.

In addition to the Adjustable Straw Cover, we also offer a range of complementary products, including the Adjustable Straw Cover in various colors, the 32oz Owala Boot, and the 24oz Owala Boot. These accessories are designed to enhance your drinking experience and provide a complete solution for your tumbler needs.
