8pcs S tanley Spill Stopper for Stanley Cup 40oz/30oz H2.0, Silicone Spill Proof Stopper for Stanley 30oz With Clear Straw Topper, Cute Cloud Straw Covers

Good quality but I ended up finding a way better price on temu so i returned it.

Helps me a lot to not spill my water, really like it. It is cheap and a very good solution for the liking problem. 100% recommended

Great for the little ones and dressing up their cups, easy non spill .

it’s good! it’s cute, the flowers are a little slanted but it’s okay

On brand and offbrand Stanley’s, these work amazing definitely worth it!!!

I carry my Stanley in my tote bag going into the office so my hands are free and this little set works perfectly to prevent leaks. I realized once in the beginning that my cup had leaked all inside my tote and onto my jacket. This little set is completely silicone, clear-ish white, and when my cup gets tilted sideways or when water is sloshing around from being carried it doesn't leak at all. Now as I'm taking these pics I held the cup angled upside down and fluid was coming down the straw in a slow drip. My cup never goes fully lateral so that's not a big problem for me. This set works perfectly for when Stan is in my tote in the passenger seat and I'm walking with it. No spills!! I love it.

They don’t stop spills as advertised

Works good. Cats paw lol. I have black cat so this is good one. Does keep from leaking. Now where straw enters cup water may slowly drip out when on its side but nothing from cats paw stopper.
