Best-selling product from Mitsubishi Pencil: Jetstream ballpoint pen This is the front shaft for the pen. Changed from the standard rubber specification to a wood specification. Easy to handle and fits comfortably in the hand, creating a one-of-a-kind custom ballpoint pen that's different from others. The wood used is purple heart. Purple heart, as the name suggests, is a wood with a unique light purple color. It has high strength and durability, and the heartwood is also resistant to fungi and insects. It is used for interior materials, furniture, decorative veneers, sculptures, etc., mainly in places where its beautiful purple color is utilized. The dimensions of the purple heart are almost the same as the original rubber. This is only the front shaft; the ballpoint pen body is not included. If you would like the ballpoint pen body included, please comment. Also, if you would like other wood types, please comment. Price negotiations are not accepted. I have also listed various other items. Please take a look if you like. #KoboMatch Thank you. #Jetstream #Jetstream4&1 #JETSTREAM4&1 #AssembledFrontShaft #MitsubishiPencil #Multi-functionPen #Multi-functionBallpointPen #WoodShaftGrip #WoodShaftCustom #KoboMatch
