We used to get these but over the years the newer designs got cheaper and less well designed. It looks like they still sell the old designs though, so that's nice.

I've been looking at these today. Which autoseal model do you have, some of the reviews on Amazon are bad.

Same here, they worked well for so many years. They’ve been slowly dwindling as kids lose lids and stuff, and I haven’t seen them in stores for.a lot of years
