LUAATT Replacement Green Water Stopper for Stanley Classic Stainless Steel Vacuum Bottles Leak-Proof (1.1 Quart/1.5QT/2 Quart)

Made of high quality materials with a strong seal. [Note] In 2019, the official classic bottle was updated with a stopper. We are selling a new model that can be used with older versions from 2019 and earlier. I am a loyal user of the 1.1 quart bottle and have replaced the stopper numerous times over the past 10 years. The recommended lifespan of a water cup stopper is 3 years. Our stoppers have been tested to ensure they are leak-proof. Adaptations may be necessary due to version issues. If any issues arise, we will proactively resolve them. This fits Stanley Classic Bottles 1.1 quart, 2 quart, and 1/2 quart. My brother has a 2 quart Classic Bottle. I gave him two to test. He said they work after the replacement. The cup stopper is slightly different from the old version, but the function is the same. If you're not sure if it will work, please contact us. This is a very good replacement. We will provide more usage videos in the future to assist our customers. Black or green optional. 1 pack includes stopper. All stoppers are tested.
