I made the grip of the multi-function ballpoint pen "Jetstream 4&1" out of wood. The material is genuine Karin (Chinese quince). Karin is a hardwood from the legume family, known for its hardness and resistance to cracking, with a beautiful reddish luster. It was finished with only a few rounds of sanding and beeswax. The size is almost the same as the original rubber grip. This listing is for the grip (front section) only. The ballpoint pen body is not included.
