This handmade pen is made from Bocote, native to Mexico and Central America, with screw-on cap, in chrome with gold plated ring.  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 wood with black streaks. The weight of the pen is 48 grams, with 0.49" diameter lower barrel and a 0.55" diameter cap.  Perfect for someone who likes a heavier pen in a dark brown color with distinctive grain.
