These are Sword Art Online clear cards purchased during the 20th anniversary of Dengeki Bunko's founding. I believe they are difficult to obtain now. I have kept them in a clear file for postcards until now, but I am currently decluttering and selling them as part of my organization. I have kept them carefully in a clear file to prevent scratches, so I don't think there are any. We cannot accept returns to prevent fraud, so please check the photos before purchasing.
