NiHome 2PCS Protective Silicone Tumbler Boot with Straw Cover for Stanley Quencher 40 30oz IceFlow 20 30oz & Hydroflask Bottle 12-24oz,Accessories for Stanley Cup-Bottom Sleeve & Straw Cover

These fit my knock-off Stanley perfectly and do a very good job of muffling the noise when setting down the tumbler. They are easy to put on. The colors are great! I really like the texture of these (the main selling point for me).

I recently purchased the NiHome 2PCS Protective Silicone Tumbler Boot with Straw Cover for my 30oz Stanley Mugs in black and grey, and I couldn't be happier. These silicone boots fit my mugs perfectly, providing an extra layer of protection against accidental bumps and scratches.The snug fit ensures stability, preventing slips, and enhancing the overall grip. I appreciate the added bonus of the straw covers, which keep my straws clean and secure while on the go. The black and grey color combination complements my mugs stylishly.Moreover, the high-quality silicone material is durable and easy to clean, making maintenance a breeze. It's reassuring to know my favorite tumblers are safeguarded without compromising their functionality. Overall, the NiHome Protective Silicone Tumbler Boots offer excellent protection and convenience, making them a worthwhile investment for any tumbler enthusiast.

This protective cover is thicker than some others on the market so it definitely serves the function of being very protective if dropped. As a consequence of this, it may not fit in all of your vehicle cupholders anymore. So you may have to decide which feature is more important. The boot slips on very easily and stays tightly on the cup. My cup isn't a Stanley brand and it still fits very well. If you want to remove it to clean, it comes off fairly easily with a little tugging at the edges. I haven't used the straw covers yet because my cup has a built in straw, but the covers are very cute and look like little Stanley cups with flowers on them. These covers are definitely worth the price!

These work great on Stanley cups. They stay on snug. The silicone material is super easy to wipe off and prevents the cup from clanking on the countertop and tables. Still fits great in the car cup holder and doesn't slip off easily. They straw cover is great too.

I really do like this set of silicone tumbler boots. It fits nicely in both my 40 oz. Hydroflask tumbler and my smaller Swig tumbler cup. These boots are thicker than a normal Hydroflask boot, if you’re familiar with those, but they will still fit snugly into my car cup holder.This listing says these are white and gray, but I received ivory and navy. The navy looked perfect, but there are some imperfections around the edge of the ivory. It’s a bit of a bummer, but I still really like this set because it fits multiple cups and tumblers and prevents the loud banging noise when sitting my cups down.

Love these stylist accessories! Fits perfectly on my Stanley tumblers

The boots are thick and made to exactly fit the shape of a Stanley cup becoming slightly larger towards the top. They wash well abd fit well.
