Huh, this is easier than using those tiny holes any way. Is there any reason I need to put the innper plug back in for use, or can I simply discard it?
It stabilizes the cup in the carto,
and also helps prevent overheating the carto shell so that it doesn't burn you
and it tries to seal the wide cup slots so that you don't get liquid in the cup and then through the air stem and all over the place
The problem is that it acts like it's oversized and it can cause a lot of movement trying to get it back on properly.
