Three items: a rapidograph (0.18mm, 0.20mm, 2 pens), a STAEDTLER 925 35-03 (0.3mm, 1 pen), and ink cartridges. Also included is a set of replacement leads. These items were used for approximately 100 sheets of drafting practice in preparation for a professional certification exam. They allow for extremely fine and clear drafting. Compliant with land and house surveyor certification regulations. The mechanical pencils have some dust in the grooves of the grip. The rapidograph nibs and the STAEDTLER nozzle are brand new, having been replaced. Based on my personal experience, when drafting a polygon with sides measuring 5m to 30m at a 1/250 scale on drafting paper, I can achieve an accuracy within ±50mm of the actual size. - Brand: rotring, STAEDTLER - Model: SEKAIDO - Type: Drafting (0.18mm, 0.20mm) rapidograph (2 pens), Drafting 0.3mm mechanical pencil (1 pen) - Lead Diameter: 0.3mm - Accessories: Replacement leads (HB), 1 box of ink cartridges - Replacement Lead Brand: Pilot - Type: Graphite - Lead Diameter: 0.3mm Both ink cartridges are installed, and a box of 3 additional cartridges is included.
