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

Purchased to fit my Frost Buddy - To Go Buddy. Fits great, easy to put on. My only issue, is when it's on, my frost buddy won't fit in my car holder, makes it too snug. So take that into consideration. However, i still use it in the house and many other places. It protects the bottom well. I bought the black one, it was as described. The glitter in the sleeve makes it look super pretty with my teal glitter frost buddy. Great value for the money. Super happy with this purchase.

Fits and stays on my Stanley cup, it falls off my Yeti. But it’s awesome at protecting my cup base. Just not as sparkly as I wanted, but I still love it.

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.

Fit perfectly on my Stanley cup. Gives it that little bling
