Silicone Boot for Stanley 40 oz Quencher Adventure Tumbler and IceFlow Flip 30 oz 20 oz, Stanley Cup Accessories Protector Bottom Sleeve Cover Bumper for Stanley 40 oz with Handle (Grapefruit)

My wife bought a nice cup and it was great at keeping her drinks cold. The only problem was if 1 drop of water was on a flat surface under the cup it would slide all over the place. This fits tight, looks good, and the rubbery texture holds it in place. Problem solved!

Fits perfect and very pretty color.

I got this to cover the bottom of my 40oz Stanley after I saw reviews of the bottom chipping. It has protected it well and is easy to take off and put back on. It does make it a little snug when it comes to using cup holders.

It’s the perfect size. I’m able to get it on and off, but it doesn’t fall off when I pull it out from my cupholder.

This is a good fit but not perfect for a tumbler cup with a handle.

I am constantly hurting the bottom of my yetti or stanley cups. So this is a perfect solution and it even took away the wobble from one that I dented originally. So is totally worth it!

Fits amazingly on my Stanley 40oz. Already saved it from a few falls.

No more slipping or knocking your cup over. This is exactly what you need.
