My relative has retired from their electrical appliance business, so these are items for disposal. I don't know the details. I've listed various electrical materials. Price negotiations and discounts for bulk purchases are welcome. Please inquire via comments. The purchase dates are unknown, so please refrain from purchasing if you are overly concerned about this. Please examine the images before considering a purchase. This is only for unopened case sales. The photo of a single lamp is from a separate, individual sale.
