4-Pack Silicone Replacement Stoppers for Owala FreeSip Water Bottles - BPA-Free Leak-Proof Seals

Great value for good product! Bought these after my original one got moldy and they are a great substitution. They are slightly bigger than the original so it makes closing the bottle a bit harder, but still does close!

Solid all around. Product works as described with no issues or quality concerns. Would buy again if needed.

As the title says, the gray ones work well. They are not exactly the same - a little thicker...so a little harder to close the lid, but not much at all. I also ordered the white ones, though - they were too thick - it would take 2 hands to close the lid. So, I returned those. Not sure about the other colors. It seems that these gray ones will work well, though, and last fine.

I ordered white, they showed up dark red. Still fits fine and is easy to switch out. they are just the wrong color and it doesn't match my daughter's or my bottle.

Works in Owala bottle, though slightly too big (have to apply pressure to get lid to close).

Fits well. We'll see how it holds up, but it looks like good quality.

This doesn't fit my owala well. It takes 2 hands or really pressing on the top to close it. It also was supposed to be white but came red
