This pen mixes wood, acrylic and True Stone (85% stone mixed with 15% acrylic).  The pen has a good weight.  The White Jasper True Stone separates the purple acrylic and dark grain of the Cocabola.  The pen is finished with 12 coats of CA glue, wet sanded to 12,000 grit and buffed to a high gloss with White Diamond grit.
