2 Pack Stanley Flip Straw Lid, Replacement Fit for 40 oz Stanley Quencher, Spill-Proof Design, High-End Anti-Fall And Heat-Resistant Material (Beige and Black Set)

This may be the best purchase I’ve ever made here! As a busy mom of two littles, a gym goer, and an always clumsy person this has been a total game changer! It does not leak even a tiny tiny bit as long as the straw part is down. I’m so impressed. I toss it into my bag constantly, it makes my life so much easier to not have to juggle a drink along with everything else. Easy to clean, I got black and it’s the exact color of my Stanley, fits flawlessly, I’ve dropped it and banged it on things many times and it’s held up no problem, no funky smells or flavor.

This is actually a great deal for the price and quality. They are spill proof and easy to clean.

I got these for my stanley cups and I must say their amazing. Its easy t clean, very durable and its makes it easier to carry the cups around. It fits perfectly but the color is a bit off. Over all it was a great buy.

I just wanted a lid that doesn’t leak. Being around kids with a Stanley has caused lots of spills. This one works great. I gave it 4 stars because it can only be positioned aligned with the handle, which I don’t like. I’d prefer it to be centered (aligned with the Stanley logo) for optimal drinking—but it’s not a big deal.

The media could not be loaded. Fits my 40 oz Stanley perfectly and is confirmed leak proof! It also fits the 64 oz BUT it is not completely leak proof, which is fine because that’s not what it was made for. I think it will last a while and it come with a cleaning brush. I pan to only use for water. Stanley are know the get heavier with liquid in them. I will try ice overnight to see how it does but overall I love it!

These fit the Stanley 40 oz well. They do not leak. I used them for a few months and was happy with them. One day I noticed some white on the side of my cup. So I screwed the lid onto my cup, unscrewed it and then checked the threads of the cup and lid. Sure enough, there was plastic shavings. I just didn't pay attention to it before. I did look up the effects of swallowing plastic since I had been doing so for a few months. The articles state it is not toxic and will pass through your system in a few days. I am giving these three stars because they do what they claimed. I would definitely rate them higher if they didn't degrade every time I used them. You can see in the pictures where the edges of the lids are worn and chipped. This is from 3 1/2 months of use, handwashing only and then screwed back onto the cup and stored when it is not being used.

Great, better than the original Stanley Cup lid. Fits my Stanley perfectly. I wish they made metal straws instead of the plastic ones, but I love this lid! It also matches my hot pink Stanley perfectly. I highly recommend.

These fit perfect onto my Stanley and are leak propf
