Upgrade 2PCS Protective Silicone Boot Bumper for Stanley Quencher Adventure 40oz 30oz IceFlow 20oz 30oz Tumbler, Water Bottle Bottom Sleeve Cover Accessories for Stanley Mug Cup(Pink)

These are so nice and durable. Fit my Stanley 30oz cup so well, protects the bottom from nicks and scratches. Dents. Grips so well, almost too well. Doesn’t come off without prying. Love the color options.

A little hard to get on the cup since it does not have a pressure release hole. Once it is on it dos a great job of preventing most bumps and reduces clanking of the cup on surfaces. Fits on most 40oz tumblers and matches any colors since it is a clear/white. Great price for what it is.

These silicone boots are amazing! They protect my new Stanley from drips, bumps, and of course drops! The size fits perfect for the 40 oz Stanley. It fits like a perfect size boot! Literally! And the color is awesome. The feel is nice to rub on even holding the bottom of the cup( I do this all the time). If you’re looking for a boot that’s gonna bring you security, this IS THE ONE!

Perfect size, they fit perfectly. The design is simple but with quality. The rubber gives more grip on it and it easy to remove for washing. We leave them on for the dishwasher and nothing happens. I got the white ones and they don't get dirty at all and if they do just wet your finger and wipe it off easily. Totally recommend even though they don't fit very well on a Tesla model Y cup holder.

Fits Stanley 40oz perfectly. Great for keeping the bottom from getting scratched/ chipped/ dented. Easy to use and fit like a glove.

I ordered this for my daughter's Stanley cup awhile ago and still holding up well. She loves it and it keeps her cup from sliding on slick surfaces. Very lightweight but good quality product. It's the perfect size for her Stanley. The color matched the picture shown. Would purchase again if I were to get a cup.

Love the color. It's nice and brite and fit snuggly on my stanley

I searched all over to find bumpers for my Stanley after I saw the bottom of it getting damaged and am glad I bought these! I have the 40oz in the color Dune and I am really big on color matching, so I picked clear since all others seem way off from what I can tell. It's not entirely clear and has a whiteish hue to it but it matches the lid of my cup, which maked me love it! It is a two pack and they are packaged in a small box with one inside of the other and both fit my cup perfectly fine! It seems like a sturdy and thick material and my cup still sits flat. I love the fit and color and would buy these again for my Stanley!

Great fit!

Me encantaron. El paquete trae 2

Ajustan a los vasos. Cumplen su función.

Le quedo muy bien a mi stanley de 30oz. Material resistente; en relación al precio lo recomiendo y ayuda mucho a que no haya fugas de liquido.

El spill stopper ajustó muy bien a mi termo de 30oz versión H2.0 y la funda protectora también
