This beautiful deer antler twist ink pen with stylus was hand crafted from a real deer antler. The deer antler is then turned on my lathe sanded very smooth and finished with multiple coats of CA glue for a durable shine. Refills can be purchased at any office supply store or online. All of my pens are unique and hand turned by myself. Each pen represents the finest in quality and workmanship. They are both beautiful and functional. The pen measures 5-3/4" I'm always happy to help. Thanks for looking!
