※ Also listed on other flea market apps. These are water-based Rasson pens from Teranishi Chemical Industry, purchased approximately 20 years ago. There are 2 black pens, 1 blue pen, and 9 light orange pens, for a total of 12 pens. They were stored in a dark place at home, but I used them once to check their condition. Also, because they are long-term storage items, there are fine scratches and signs of use. Please be aware of this. I confirmed that all 12 pens are still usable (see image 3). If you have any questions, please feel free to ask in the comments.
