Mitsubishi Pencil's best-selling ballpoint pen, Jetstream, replacement front section. 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 Bubinga. Bubinga grows slowly over many years, so it has a very high density compared to coniferous trees, and the wood itself is hard and has a substantial weight. Being hard means it is also resistant to abrasion, and using Bubinga wood for furniture and interior materials makes it less likely to get worn or scratched, maintaining its beautiful appearance. In addition, the dense and heavy Bubinga wood is also used for musical instruments such as drums and guitars. Using it for musical instruments allows for clear and sharp sounds, and it also has the characteristic of quick sound onset. The dimensions of the Bubinga are almost the same as the genuine rubber. This is only the front section; 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 #Multi-function pen #Multi-function ballpoint pen #Wood grip #Wood custom #Replacement front section #Mitsubishi Pencil #KoboMatch
