New Old Stock. All this information is from the net and so I don’t feel responsible if incorrect. Some packaging was opened to inspect quality, and some are soiled and shop worn and crumbling foam package backing was replaced if necessary. The price is right so no returns and sold “as is”. Please take time to look at my other auctions and sales. Thank you and good luck!
