This distinctive handmade rollerball is made from Figured Walnut, native to North America, 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 near black with subtle black figuring. 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, figured dark brown wood pen and clean design.
