40 oz Tumbler Lid for Stanley, 2 Pack Tumbler Filp Straw Lid Replacement, Spill Proof Splash Resistant Tumbler Cover for Stanley Quencher Cup (Frost)

Highly recommend if you need to make your Stanley a leak proof cup. The two pack works perfect on my 40oz Stanley. They are easy to use and clean between uses. The straws a great amount of water to come through it for staying hydrated. When it’s closed no water escapes so this is great for spaces where your drink could possibly be knocked over. This lid also allows me to throw my cup in my bag for traveling. I love these!

This set of replacement lids for the Stanley 40oz tumbler are very nice quality and fit the cup perfectly. The folding straw design is nice and it does create a solid, spill-proof barrier when in place.

Squeaked when sipping. I gave it 2 stars because it was leakproof but the squeaking was just too loud.

The lid fits perfectly. The ‘straw’ isn’t a straw. It is fish tank tubing. The cuts on the ‘straws’ are uneven and jagged. The diameter is too small to fit on the lid. I tried to warm the plastic to make stretching easier and it didn’t work. Save your money. I returned it.

I have some Stanley cup and want to buy lids for them, so I got these off of Amazon, which is great because it came in a two pack with two straws for a valuable price.

This is a good fit as a replacement lid. No leaks or any problems. It doesn’t fit other non-named Stanley mugs, so make sure you are selecting this for the appropriate replacement.

It worked perfectly on my Stanley Quencher, was able to place it on and tested that it does not leak whatsoever, love it!

I love my Stanley and I love it even more now that it is spill proof.
