About this item

• Made of high quality materials, strong sealing
• Note: In 2019, the official classic bottle has been updated with the stopper. What we sell is the new modle, which can be used with the old version before 2019. I am a loyal user of 1.1qt. I have changed the stopper many times in the past ten years. The recommended service life of the water cup stopper is 3 years. Our stopper have been tested to ensure that they will not leak. Because of the version problem, it may need to adapt. If you have a problem, we will actively solve it for you
• Compatible with stanley classic bottle 1.1qt., 2qt., and 1/2.My brother has a 2qt classic bottle . I gave him 2 for test. He said that they could be used after replacement. It is a little different from the old version of the cup stopper, but the function is the same. If you are not sure whether you can use it, you can contact me. This is a very good replacement. In the future, I will provide more use videos to help my customers.
