Although it is unused, it has been stored at home, so please be sure to check the condition before purchasing, and only purchase if you understand. I am not considering lowering the price, but I will periodically review the price if others list the same product or if it does not sell for a certain period of time! *The ruler in the photo is not included. *Returns are not accepted to prevent exchanges. *Listed as very rare because there are no other listings of the same item!
