Ah yes, that could actually have been me buying the last ones.
I bought a couple last week, as the two Kielers I have queens in were starting to look a bit crowded (I've held them waiting for a couple of hives that were in the process of rearing their own queens to act as spares). I was worrying about them upping and leaving.
I've got them sat on top of both now with some home made top bars, I can't do grooves in them, but the bees don't seem to mind!
