WUQIDProtective Bling Silicone Boot Sleeve, Compatible with Stanley Tumbler 20-40oz & Hydro Flask Bottle 12oz-24oz, Glitter Reduces Dents Sleeve Cover for More Bottles/Tumblers Bottom of 2.83-2.95in

It’s worth the money, perfect fit, and very easy to install. The color is perfect and the pink is bright and sparkly.

This is a very nice boot which fits my 40 oz Stanley perfectly. I love the color. I always put a smidgen of flour in a new boot, rub it all around and have no problem slipping it on to my large Stanley.

If you’re looking for some glam to spice up your 30 ounce Stanley cup this is it! Super cute, works well, slides on off easily and does the job!

Its very pretty however its a very tight fit and took some time getting it on.

Perfect fit for Contigo 40 oz. Snug to get on but that’s ideal. Would definitely buy again and would gift with tumblers!

I didn’t read the product size information and stupidly thought all 40 oz water bottles were the same. It was a little difficult to put it on but it still fit even though the circumference of the water bottle was around 6 cm bigger than the bumper. Amazing stretch and looks cute.

I love that this boot is see through so you can still see the design of my cup, but also it adds a touch of glitter which I love. It's exactly what I was going for and matches perfectly

Beware! The product I received is beautiful but only fits certain Stanley tumblers, depending of the type of paint. The boot is shiny and slick on the inside and matte on the outside. It sticks to the neon green so much that it can’t be put on because it has a glossy finish. However, it fits perfectly on the matte pink.

I paid $20 for it, so a bit pricier then other ones but... I love the sparkle. It matches so well with my tumbler like I was hoping for.

Protege bien el vaso, va ajustada y no se sale. Lo recomiendo.
