Premium Food-Grade Silicone

Made from premium quality silicone rubber, our protective silicone stoppers are both safe and reusable. Crafted from high-grade food-grade silicone, these spill stops ensure a premium and safe drinking experience. You can enjoy peace of mind knowing your health is always a top priority.

Precise Fit

Our silicone spill-proof stoppers are specifically designed to fit 40 oz Stanley cups and 30 oz tumblers with handles. Precisely engineered, they match the exact dimensions of your favorite tumbler, providing a snug and secure fit.

Spill-Proof Protection

Installed in the straw hole of the lid, these spacers not only form a seal but also hold the straw in place. This design effectively stops debris and dust from entering through the straw, significantly reducing spills and providing an improved leak-resistant solution.

Straw-Friendly Design

Our silicone spacers come with 4 straw cover caps, 4 square spacers, and 4 round leak stoppers. The straw cover caps are compatible with straws less than 0.39 inches (10mm) in diameter, ensuring more convenient drinking with most straws.

Easy Installation

Installing our spacers is incredibly straightforward. These accessories can be easily inserted and pressed down firmly. You can use them hassle-free, whether you're traveling or using them in your daily life. The spacers will keep your drinks inside the cup and prevent surrounding mess.

Patent Pending

Our Stanley cups come with two versions: Silicone Spill Proof Stopper 1.0 and Silicone Spill Proof Stopper 2.0. If you have version 1.0 or 2.0 Stanley cups, you can choose the size that best fits your needs. The 6-piece kit is designed to fit both versions.

These unique features make our silicone spacers an ideal choice for anyone looking to enhance their drinking experience, especially when using Stanley cups.
