A Straightforward Breakdown

Easy-to-Open and Close Lid Design

Our sliding cover design makes opening and closing the lid incredibly simple and convenient. The top hole can be used directly or with a straw for ultimate ease. Plus, the sliding cover ensures you won't touch your nose while drinking!

Excellent Compatibility

This lid is perfect for 30 ounces of insulated stainless steel cups of any material, except RTIC flat-bottomed cups! Before purchasing, please measure the inner diameter and outer diameter of your cup. Refer to our fourth and fifth pictures for detailed measurements taken by actual testing.

Splash-Proof Lid

The flat-bottomed lid is lined with a silicone gasket to prevent splashes and major spills when turned over. An air hole at the top of the slider helps to reduce splashing. While we strive for a leak-proof design, please note that no lid is 100% leak-proof. Use with caution as described in the precautions below.
