I customized the grip of a Dr. Grip 4&1 with Purpleheart wood. This is a slightly defective item with a small chip on the clip side. It can also be used for the Frixion Ball 3 Metal. It has a combined finish of glass coating and beeswax wax. This listing is for the grip part only. Please note that the metal tip and the pen body are not included. Only the parts in the last photo are included. I am not considering price reductions. There is no warranty. It will be shipped via Nekopos. Shipping will be on weekends due to my schedule, so it will take some time. About Purpleheart: It is distributed in tropical regions of Central and South America, including southern Brazil. Immediately after being sawn, it has a vibrant purple color, as the name suggests, that is hard to believe is natural. Over time, when exposed to ultraviolet light, it gradually changes to a deep purplish-brown. Despite its flashy appearance, it is a material with excellent durability and decay resistance. Thank you for viewing. I love stationery and use Jetstream and Dr. Grip 4&1 pens. I dislike the deterioration of the rubber grips, so I started making them for myself using scrap wood from the famous trees I used to collect. You can customize these practical pens to your liking, just like changing your smartphone case. I hope that my wooden pen shafts and wood parts can be of some help in your daily work, studies, tests, qualifications, and entrance exams. For those who like handmade wooden pen shafts, those who like the works of wooden shaft workshops such as Craft A, Nohara Kougei, Koubou Setsuri, Kobuta Koubou, etc., and those who like multi-function pens such as Jetstream 4&1, Dr. Grip 4&1, and Pure Malt Premium 2&1, how about it? I create them using famous woods such as Karin Kome, Karin Kouhaku, Snake Wood, Pink Ivory, Desert Ironwood, Black Persimmon, Black Persimmon Peacock Grain, Red Sandalwood, Ebony, Rosewood, Sandalwood, Palo Santo, Briar, and Rosewood. #jnsm
