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.
