Mitsubishi Pencil's best-selling ballpoint pen, Jetstream, replacement front section. Changed from the standard rubber specification to a wood specification. Also, the front section has been changed to a matte black color for a sophisticated style. Easy to handle and fits comfortably in the hand, with a custom color scheme unlike any other, making it a truly one-of-a-kind custom ballpoint pen. The wood part is black walnut. Black walnut is one of the world's three major fine woods and is used in a wide range of fields, including furniture, building materials, and musical instruments. Above all, its attractive feature is its unique, high-class, deep color. Also, the contrast between the deep color of the black walnut and the matte black color of the front section gives it a luxurious feel. The dimensions of the black walnut are almost the same as the original rubber. The front section has been polished with sandpaper after the original plating, and then black rust processing has been applied. The paint is matte black, with five layers, and finished with one layer of clear coat. Only the front section is included; the ballpoint pen body is not included. If you wish to include the ballpoint pen body, please comment. Also, if you would like other wood types, please comment. Price negotiations are not accepted. I have other items for sale as well. Please take a look if you like. #KoboMatch Thank you. #Jetstream #Jetstream4&1 #JETSTREAM4&1 #Multi-function pen #Multi-function ballpoint pen #Wood grip #Wood custom #Assembled front section #Mitsubishi Pencil #KoboMatch
