These are my 1st Sierra pens, one is cactus cast in clear resin the other is whitetail deer antler. On the cactus I painted the inside of the blank black and the tube also. I felt kinda cheated , these pens go together so easy. Sorry I didn't get a better picture of the cactus pen:frown:. As always thanks for looking and all comments good and bad welcomed. :biggrin:
