This handmade pen is made from Thuya Burl, native to Morocco, 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 given a protective varnish. This is obtained from the roots of thhe Thuya tree, with very distictive medium brown color with dark brown figures.  The weight of the pen is comfortable at 37 grams, with a larger diameter that fits your hand well.  Very distinctive pen for someone who likes a highly figured brown grain.
