KATO model train parts "11-702 KATO Coupler N (Black)". Compatible with Arnold coupler pockets, 20 pieces included. As a bonus, 5 Coupler N JP A are included. I have stored these unused since purchase. They are new and unopened, but the packaging may have some scratches due to home storage. Please refrain from purchasing if you are looking for a perfect condition item. How about it for those looking for maintenance parts or additional/replacement parts for model trains?
