It would be great to see an example of where the straw actually goes. You show an image of how this is “leakproof”.
The “hole” for the straw is not circular. I’m a beginner. I don’t know 🤷🏼♀️ where the straw goes.
Thank you 😊

Could be better
So I bought this lid and stopper both very well made HOWEVER when you go to put the stopper in the hole it pushes the lid in , after a frustrating 10 minutes of re setting the lid band I finally got the plug in without any problem, and so if you don’t have it just right with the correct angle and pressure it won’t go in, but I don’t have time to sit there and keep trying over and over, I will say though it doesn’t leak which is a plus
I agree that it takes some practice to get this right. The trick is to twist the plug back and forth while pushing it in, and once you figure that out it should be pretty easy.
