I've customized the Pure Malt 4&1 grip with black buffalo horn. I made it from black buffalo horn, which is used as a material for seals. Enjoy the unique feeling of being shiny yet non-slip, as if it's clinging to your fingers. The pen is new. I'm not considering discounts. There is no warranty. The box will be folded and shipped via Nekopos. Shipping will be on weekends due to my schedule, so it will take a little time. For those who understand handmade items, how about it, including shipping? About Black Buffalo Horn: I used the highest grade of black buffalo horn, which is also used for seals, generally called "dye-free." It's a high-quality part that doesn't need to be dyed like other black buffalo horns, and it has an attractive, luxurious black luster. Black buffalo horn's main component is protein, and it is characterized by being weak to dryness. When storing, you can put it in a case and occasionally wipe it with paper soaked in oil to make it last longer. Thank you for looking. I love stationery and use Jetstream and Dr. Grip 4&1 pens. I don't like the deterioration of the rubber, so I started making them for myself using the scraps of precious wood I had collected before. You can customize these practical pens to your liking, just like changing your smartphone cover. I hope that my handmade wooden pens and wood parts will be of some help in your daily work, study, tests, certification exams, and entrance exams. For those who like handmade wooden pens, those who like the works of wooden pen workshops such as Craft A, Nohara Kougei, Koubou Setsuri, Kobuta Koubou, 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 use precious woods such as Karin瘤 (Karin burl), Karin Kouhaku (Karin red and white), Snake Wood, Pink Ivory, Desert Ironwood, Black Persimmon, Black Persimmon Peacock Grain, Red Sandalwood, Ebony, Rosewood, Sandalwood, Palo Santo, Briar, Rosewood, and Satine. #jnsm
