look in and select which comb you wanted to take and cut or break it off.
so no removable frames? seems to me you could do removable frames without much trouble. someone would have to invent something to lift loose the first frame you wanted to pull but after that, sliding them free shouldn't be to hard. a regular hive tool would do it.
I actually like the design but the 2 reasons I think they are no longer popular is the lack of removable frames, which I do think could be easily redesigned; and a hinged door, which most certainly would get glued shut with a huge amount of propolis.
