Mitsubishi Pencil's best-selling ballpoint pen, Jetstream, front shaft. Changed from the standard rubber specification to a wood specification. Easy to handle and fits in your hand, making it a one-of-a-kind custom ballpoint pen, different from others. The wood used is padauk. Padauk has a beautiful vivid vermilion color and is a highly durable wood. It has good properties such as being resistant to rot and wear. As for its uses, the reddish heartwood is beautiful, so it is popular as a material for interior materials such as floor pillars, furniture, and counter materials. It is also used for keyboard percussion instruments such as xylophones and marimbas, and materials for guitars. The dimensions of the padauk are almost the same as the genuine rubber. Only the front shaft is included, and 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. Please refrain from price negotiations. 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
