In the 60s, at least, the strings of miniature lights were Italian made. The last sets I saw several years ago were made in China and there was a warning about wearing gloves, washing up after handling and not allowing children to touch them because of the lead residue on the sets. I don't know how the lead got on the sets unless it is part of the atmosphere in the Chinese factories. American corporations have the factories there because they can't have lead in the air in factories here. Pity.
