Hi John and welcome. Since the members here are customers as well, I would ask Buds Customer Service directly for details at 1-859-368-0371 9am-8pm EST Mon-Fri. or use the Blue Chat now button at the bottom right corner 9am to 8pm Mon - Sat and 9am to 7pm Sunday.

While it is being sold as "Used" it could be that the condition is "New"?
Someone could have bought it, refused it at FFL, keeping it in "New" condition?

I cant find a definite answer I think they are new however I suggest that you Contact Buds Customer Service by using the Blue chat button at the bottom right side of the page and ask them for clarification. We are not buds employees we are volunteers that answer questions.
