AUAUY Straw Covers Compatible with Stanley 30&40 Oz Tumbler, Silicone Tips, Reusable Protectors - 4PCS

Stanley cup now completely leak free 😀

This is a great set for a Stanley quencher, however I did have to pierce a hole in the round leak stopper in order to allow for air flow, without doing this the round leak stopper kept falling off into the drink and prevented you from being able to drink through the straw. It was easy enough to do with a pair of scissors, I created a small hole by inserting one end of the scissors. By doing this the silicone does still close back up but allows enough space for air to flow through, without creating a large enough hole for water to leak through. Overall this set does work for what I required, you’re unlikely to be able to put the quencher in your bag without fear of leakage but it does prevent water gushing out if the bottle is knocked over accidentally.

This is a good idea, was able to seal hole in cup ,

Bought for a non-branded cup from a blue&yellow store! Fits well, the inner valve I’ve cut and adapted to fit securely to keep cup water tight. It doesn’t stay put otherwise But you could just not use that part if your just after the straw cover.

The main round bit keeps falling down, the rectangular one also not seals it very well, you can feel more airs with straw. Returned it

These covers are my good too. For on all types of straws and are easy to wipe clean.

With all three parts fitted , it doesn’t leak at all even when shaken. I do find the middle one makes it make a noises when drinking through the straw so I took that off, but still doesn’t leak if knocked over which is exactly what I wanted .

The rubber cover that goes over the inside rotation hole never stays in place, constantly falls into the water in which case means the Stanley still leak whenever it falls over. Literally redundant to sell this product, but the rubber part that closes the straw gap works perfectly.

They are good, fits well, looks good

Je suis contente l'ajout des 3 embouts en silicone permettent à mon mug stanley d être enfin étanche. Merci (quencher H2O 40oz)

No son para Stanley, queda un poco grande, hay que aplicar calor para que quede bien.
