Thank you for viewing. This is a Nakayoshi magazine supplement from 37 years ago?? It's a penguin stationery set by Yu Asagiri. However, I don't know how many sheets were originally in the set, and it looks like a few have been used. The design has two color variations per set. There are 12 sheets. The memo paper is starting to peel away from the backing. Please only purchase if you understand this.
