I am selling a new, unused, genuine KEYENCE OP-87988 MK-U6000 type filter A&B set, as shown in the image. I am offering free shipping. I no longer need it because I replaced the printer I was using. I'm selling it for less than half the retail price, at the lowest possible price. I don't think you'll find a shop selling it this cheap. There is only one item, so it's first-come, first-served. Shipping will be via Yu-Packet Plus (anonymous shipping), and it's free. If you need it, please purchase it. This item is not subject to price reduction.
