I’ve now bought three sets of these - one for my Stanley, and one for two different friends because they were complaining about their Stanleys leaking too. And it WORKS. like amazingly well. I love all the color options, they match any Stanley. It’s super easy to use and straightforward, and it fits great on my cup. Read more
I adore these stoppers. They fix what the premium cup “brand” couldn’t or wouldn’t. Stops all leaks. Fit well. Works well. Nice color. They will create a much stronger suction when drinking from the straw. I use a silicone straw and will gently press the straw away from the seal wall in order to let a small amount of air flow through to help offset the internal pressure. These seals are awesome.

Fit perfect and is definitely leak proof once installed correctly. Easy to clean also. Read more
My set was missing a straw stopper (only received 5 pieces - 2 round, 2 trapezoid and only 1 straw stopper). The little plastic container it was shipped in opened and I guess the straw piece fell out the slit in the box. As far as the quality, Amazing!! I love the color, and it does exactly as it says - my Stanley no longer leaks now from the top. The price makes it totally worth it. I definitely would buy again and highly recommend. Read more
I got the Fluted Wisteria Shine cup for Christmas. It doesn't keep anything cold. My husband said it was because of the holes in the cup. I bought these hoping they would help. They don't. The cup isn't as described. It's a pretty cup but not very useful :( Read more
Ever since I got my Stanley I had the problem of it constantly spilling. I can't put it in my backpack because it can't fit in the side and if I put it into the actual backpack it might mess up my work so I had to keep it out of my backpack and it would constantly spill in class or when I would walk with it and it was extremely annoying. I got this to aid with that problem and it works really well. I can completely turn the cup over and not a single drop comes out. The stopper might look too big for the whole but trust me it goes in there and it's pretty snug. My straw stays completely still too. The only thing I don't like about it is that they're isn't any designs available for the straw topper but the good thing is that I can take my existing straw topper and use hot glue to put the design on. Would definitely recommend and would definitely buy again if needed. Read more
Works well. I like that it is so small. Read more
It definitely keeps the beverage from spilling but it also makes it hard to get the beverage out. I feel like I’m using a sipping cup. Read more
