O.K. for moving bees from commercial b.breeders but a bit on the thin side to use as a long term neuc.Jon from N.I. has made some from ex election boards (correx board) and I think has used exp.poly inside as tempory insulation.
I thought he wanted a template to make them from old election boards - possibly for people collecting nucs. I don't think he is used to answering questions, or doesn't look at his threads very often.
