These are postcards that came as supplements to Bessatsu Margaret, purchased about 10 years ago. They are a set of 16 cards featuring Nijiro Days, Kimi ni Todoke, Ore Monogatari!!, Sensei Kunshu, Ao Haru Ride, Wolf Girl and Black Prince, Ao Haru Ride, Strobe Edge, ReRe Hello, and honey. They have been stored in a dark place at home. Thank you for your understanding.
