2 Pack 40 oz Tumbler Flip Straw Lid Replacement fit for Stanley Quencher, Spill Proof Splash Resistant Tumbler Lids,Dustproof Tumbler Cover, Reusable Tumbler Cover，With straw(White)

It fits perfectly and, best of all, it doesn’t spill at all. Whether I’m on the go or carrying it around, I don’t have to worry about leaks or accidents. Great quality and a must-have for anyone with a Stanley bottle

All the influencers swear these are leak proof. Well they’re not. They leak the same as the Stanley cup one. They also pool condensation on top of the lid. I’d say skip this purchase and stick with your Stanley cup lid

Love that it’s spill proof! I like this lid much better than the other one. Only thing that sucks is cleaning it.

Had to replace my lid and this worked perfect for my large Stanley cup

Purchased this two pack of lids. One of the lids fit my cup perfectly, the other did not. It is like one millimeter too small and therefore doesn’t thread on the cup. So it’s 50/50. I have one good lid and then one that I’m just going to have to discard because it doesn’t fit any cup I have.

We ordered this lid set two times. For both of them the black rubber rim would not stay on and had to be put back on. The flip straw worked fine.

We love these so much! Awesome quality, durable and 100% waterproof! We love our stanleys but they spill too easily so this was a life saver!

Not spillproof. Leaked water out of the rim on a 40oz Stanley
