These are 5 badges from Nitchinoken (Nihon Nōken) that I received for attending lectures and mock exams two years ago. All are unused and still in their original plastic wrapping. There are no noticeable scratches, as far as I can see. I apologize if I missed anything. These items have been stored by a private individual. I would appreciate your understanding. The size is approximately 3 cm x 3 cm.
