This Bolt action pen is made from real deer antler. You will receive the one pictured in this listing. This pen was created by hand on my lathe with careful precision and attention to detail. The "Bolt Action" rifle cam is the mechanism used to extend and retract the ink cartridge. The Deer Antler is finished using multiple coats of (CA) which is a super tough, long lasting, crystal clear finishing product! Pen measures 5-3/8" long. This pen is ideal for the hunter or outdoorsman. Thanks for looking and don't hesitate to contact me with any questions.
