WORBSS Glitter Silicone Boot Sleeve for Stanley Cup H2.0 Tumbler 20 30 40oz & Hydro Flask 18-24oz with 2.85-3.0 inch Protective Anti-Slip Bottom Cover Bumper Accessories for Water Sport Bottles

Fits my Stanley brand cup perfectly. The silicone helps reduce the potential to accidentally knock the cup over. I love the glitter and am happy with the purchase. I hand wash.

I bought the Transparent Silver (translucent white with silver glitter) boot sleeve for my new white Stanley Quencher FlowState H2.0 tumbler to protect it from scratches. It looks good - I like the subtle glitter effect - and it does protect the bottom, so it does what it's supposed to do, and at a good value.Mine came packaged flattened and when it popped up it had a wrinkle on both sides, which doesn't really matter, it's just a thing that bugs me aesthetically. The fact that the boot fits loose, however is kind of a problem because it stays behind in my car cupholder when I pull it out. If I'm not paying attention, I could lose it if I were to be in someone else's car, or an Uber, Lyft, etc. My car cupholders are rubberized, as many are, so that is probably part of the problem. I will add images to this review later showing the wrinkles in the silicon. I think that if the boot fit more snugly, those wrinkles would not be visible.All in all, the boot does protect the bottom of the tumbler and while it fits looser than I would like, it is not so loose that it will just fall off randomly, so it's still usable. In my opinion, a taller boot sleeve would be a better option.

I have had this for over a year now, I use it with my light grey Stanley. I was expecting it to discolor over time but it hasn’t! Love it and worth the price. Great quality and easy to install, it may be a little misshaped in the packaging but took shape to the cup just fine. I can see the sparkles and my Stanley doesn’t make the loud clunk when putting it on a table. Isn’t slippery either.

This fits perfect on any Stanley! It adds that right amount of cuteness ❤️

I've been using this silicone sleeve for my Stanley for almost a year. I love that its so easy to slip off and throw in the dishwasher, but it stays put during use without falling off. It's super easy to use and functions great with standard sized cup holders. After many washes, the sparkles are still noticeable. I would buy it again!

Fits my 18.6-oz Philips GoZero perfectly. Got it to protect the new bottle because the bottom of my old one is all scuffed up. Knocked off a star only because some of the glitter came off on my hand, and I have a deep hatred for uncontained glitter. If you don't share that particular ick, consider it a 5-star review.

Love this! Makes the cup quieter. I was accidently banging my stanley on surfaces and this makes it so much better!

I dropped my Stanley cup and dented the bottom which caused it to wiggle. I bought this to put on the bottom and now I have no problem with my Stanley cup. Very easy to use and pretty.
