This handmade pen is made from Curly Koa, native to Hawaii, with a screw-on cap.  It uses a Schmidt 888 fine rollerball refill in black, which is easy to replace when needed, and readily obtained on Amazon, and sometimes at local stationary stores.  It's hand turned on a lathe, sanded, and give a protective varnish. This pen used a premium koa wood blank that is highly figured with color bands.  The weight of the pen is comfortable at 36 grams, with a larger diameter that fits most hands well.  A very distinctive pen for someone who likes a highly figured reddish brown wood from native wood.
