## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality seal set
*by L***C on June 24, 2025*

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.

### ⭐⭐⭐⭐⭐ Great for on the go or kids
*by A***R on June 18, 2025*

Picked these up for my daughter because she had a bad spill with her Stanley , she finds these to be well made they stop any leaks so they work well. Fit her lid and straw like a glove and make it a little more water tight

### ⭐⭐⭐⭐⭐ No More leaks
*by B***  on May 12, 2025*

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.
