This was quite popular about 25 years ago? It's a memo pad with a Katoken postcard. The memo pad has 5 colors, with the same pattern. It's been used a little bit. There are stains and scratches, as seen in the first and eighth photos. It was used back then. I think there is also age-related deterioration. I think it's a rare item that can't be obtained now.
