I engrave the artwork into naturally shed elk antler, and then hand-paint it with rich color using a 10 power magnifier and a very small brush. For the cap, I chose to use satinwood which is indigenous to the same area as this bird in order to keep them in their natural habitat so to speak. I have chosen to use bronze fittings to keep with the vintage nature of this particular pen. It will arrive to you with a medium point German made nib, a piston converter, an international ink cartridge, and a black display case which has a glass lid.
