Hybridz pen blanks are meticulously hand-crafted from Australian Mallee Burl, Buckeye Burl, Tiger Oak or Pine Cone and cast in various colored Alumilite resins. The high pressure process penetrates the pores and voids in the burl. You’ll find these blanks easy-to-turn as this special type of resin limits chip out. No two blanks are alike. For best results, finish with CA glue. (Note: As with most burls, some small voids may need to be filled with CA glue.)
