Thank you very much for viewing this item. This is the OHTO ProMecha p1009 0.9mm drafting mechanical pencil, which is now discontinued. It works without any problems. I purchased it from a stationery store a year ago and have kept it at home without ever using it. It is equipped with a guide pipe adjustment function, allowing you to adjust the length of the guide pipe. #Drafting #Discontinued #MechanicalPencil Type...Drafting mechanical pencil Body material...Metal
