I loved the price of these and they have worked great and stops leaks. I liked the appearance as it’s not as bulky as other ones I’ve seen. Easy to clean.

I was a little skeptical about ordering these stoppers, but they actually work! They are amazing! These little rubber stoppers really do make your Stanley cup spill proof. The price is great and you get 2 sets in your order!! Will definitely buy again. Absolutely recommend these for your Stanley Quencher H2.O Flow State 40 oz, perfect fit!

5.0 out of 5 stars Totally Leak-Proof!

Got these for my 40oz. Stanley and immediately had to try them out. Washed and installed all the pieces, filled my tumbler and turned my full Stanley upside down (over the sink because I was skeptical at first). Not even a SINGLE DROP of water came out! Couldn’t recommend them more!

This was amazing I used it on both a 40oz Stanley and a 30oz Stanley. Will buy these each time I buy a new Stanley!

I love my 64 oz stanley, but I hate the leaking.. this product really does stop it from spilling. I tipped upside down and shook it. No water came out!

5.0 out of 5 stars Stanley without the spills
Reviewed in the United States on June 24, 2024
My daughters, like most girls, wanted a Stanley cup. I did not want the spills! That’s a lot of water in the floor! These stoppers help!!! They make a drop of a Stanley not the rushing waters it once was! They are easily removable for cleaning! Great quality! The size is perfect for the 40oz but also works for the 30oz with a little work. Great product!

Good product that definitely stops leakage/dripping. Only drawback is connection strip between cap breaks easily
