This is a Pilot S Series 0.3mm drafting mechanical pencil. I am selling eight of these together. I enjoy stationery and have bought quite a few over time, so the number has increased considerably. I've decided to sell these 0.3mm pencils as a set. ★★These are all "0.3mm" mechanical pencils. Please be careful not to mistake them for other thicknesses. ★All items are new and unused. I have tested each one by writing with it to ensure there are no defects before listing. Please understand this. ★All erasers are also unused. ★The colors are transparent black, transparent red, transparent yellow, and transparent green. There are two of each color, for a total of eight pencils. If you'd like, why not get these colorful drafting mechanical pencils as a set? Thank you very much.
