I was using these for work. Some items are completely unused, while others have been used and have a reduced quantity. They have been stored at home, and the plastic packaging has deteriorated. I apologize, but I am unable to accept price negotiations or similar requests at this time. ★Regarding shipping: I may change the shipping method from RakuRaku Mercari便 to YuuYuu Mercari便 (or vice versa). If you have any preferences regarding the shipping method, please contact me before purchasing. ★Please review my profile before purchasing.
