MIWA Cylinder for Auxiliary Lock MIWA NDR Series For Door Thickness: 33-42mm Stainless Steel Color (Silver) Includes 3 Keys Brand New, Unused This cylinder has a reverse master key system, so it cannot be used for work, hence the low price! Although it is a new, unused item, there may be some minor scratches that are barely noticeable. Please be aware of this. I believe this is the lowest price available. *Price negotiations are not possible. (I believe this is the lowest price online. I will only offer a discount if the same product is listed at a lower price, and for no other reason.) *Receipts cannot be issued. Please review the profile before making a purchase. Cancellations requested by the buyer will not be accepted. (Inventory Control Number) as/SA #k41719
