You have to make the top of the stopper flush with the lip of the glass or else the rubber stopper will slip out. Almost lost a batch until I realized the stopper was loose.

I bought these for a different purpose than intended. Unfortunately, it didn't meet my needs and I returned them. The return process was quick and easy. I love Kohl's drop off.
