I'd like information about sources for the small, numbered, colored plastic
tags (5 colors) that I've seen for marking queen bees.  Referred to as
"Opalith-Plattchen" in German, and made in Germany I believe.  Sources in
the U.S. would be most convenient, but I'd be glad to receive information
about sources in Germany too.
