Yes, I have a can holder, one of those things that keeps a chilled can cool a little longer. Well, I have two or three. One even has the reputation of being prison issue, but it was not issued by a prison, though I could see it in a prison gift shop. I won't show it here, however, because of other considerations.
Instead, here's my favorite.
It's a little longer than the average koozie, and it fits the larger, 24-ounce cans much better. There's another here that's identical, and it sees use holding my little camera. If you ever visit, we'll set the camera aside so you can have a red koozie too.
Not pictured here is one that is similar but much larger. It is handy with a 40.
