Leak Stoppers Accessories Set For Stanley H2.0 40oz/30oz Tumbler, Includes 2 Set No Spill Stoppers and Straw Covers, Leak Proof Stoppers For Stanley Lid (6 Pcs)

The Stanley itself isn’t leakproof, no water bottle with a straw is leak proof ahah. This product has made my Stanley leak proof though! I have a 30oz Stanley, and it took some maneuvering to get the straw part to fit, I had to fold it and then place it through, that’s the only way it fit! However, it works great. I definitely recommend, plus it comes with two so if you have multiple Stanley’s, or even a friend who could use something like this then it’s perfect! The price is great too. Very easy to clean!

If you’ve knocked over your Stanley (or other affordable 40oz cup) you know that panicked feeling that 40 ounces of liquid is about to be everywhere. These really help mitigate that! They fit in the openings on the lids and really help!

The biggest problem with the Stanley's is they are leakproof. However, I no longer have this issue. Very easy to install and work great!

This is the perfect add-on to your Stanley cup to prevent leaks! I love that I can bump it and not have to run for a towel to dry up the puddle. The leaking is my biggest complaint about the Stanley Cup and this takes care of it!

I bought this for my teen’s Stanley mug. She’s a hot mess and spills stuff all the time. The second this was installed the leaks stopped. I was thoroughly impressed with it.She even flipped it upside down to show how it doesn’t leak. Which I was not a fan of! But, it didn’t leak. So, there’s that. Highly recommend for your Stanley. This was used on a 40oz Stanley 2.0 model.
