OUSHIBU Upgraded Stanley Spill Stopper Set Stanley Quencher 1.0/H2.0 w/ Handle 30oz/40oz Cup Accessories，2 Straw Cover Cap，2 Square Spill Stopper & 2 Round Leak Stopper (Pink+White) (ST20230516)

The media could not be loaded. Super cute and really works! No more spilling! There’s a silicone that goes inside as well.

But make sure to but spill stoppers and draw cover because it is not leakproof but it is a great dupe.

This product worked well converting a traditional Stanley top into a leak-proof one.

Check out the pictures for reference. I purchased this set with the intention of giving my old black stoppers to my husband, who owns black chroma tumbler. Unfortunately, the round stopper in this set is smaller than my previous one and doesn't fit my tumbler properly. Despite the initial promise, it didn't meet my expectations. Regrettably, I'll be returning this item.

Good quality and work as designed. Its cute and no water spilling from Stanley bottle. This product is for Stanley Quencher 1.0.

So I was hoping to get the pink mini cup straw stopper when I ordered this. However it did not come with it. I received the 2 round and 2 square stoppers. Along with one clear straw topper, but the pink mini cup straw stopper pictured did not, I repeat DID NOT come in the package. I needed the spill proof kit for my cup, and the whole reason why I specifically ordered this one was for the pink mini cup straw topper that was supposed to come with it. Needless to say I was disappointed when I received everything else but that.

This is supposed to make your Stanley Quencher leakproof but it doesn't. It helps with the leaking but doesn't fix the problem. I gave 2 stars because I will still use it as a straw cover, and it's cute. I wouldn't buy it again though.

Small and break easily
