This distinctive handmade rollerball is made from Curly Koa, native to Hawaii, with screw-on cap in chrome.  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 given a protective varnish. This is dark brown with darker brown to black streaks and bands. The weight of the pen is 53 grams, with 0.50" diameter lower barrel and a 0.56" diameter cap.  Perfect for someone who likes a heavier, domestic, highly figured medium colored wood pen and clean design.
