Unique, elegant or sophisticated are several words you might use to describe these pen blanks. Tru-Stone Pliable pen blanks are made from approximately 85% natural stone ore that is pigmented and combined with a gem resin. The resin, which is specially formulated for the pen turning industry, allows for higher heat tolerances so the blank is less susceptible to fractures or breakage when using standard woodturning tools. Sharp tools are a must, but when turned and polished the natural stone appearance is stunning. Available in 3/4" x 3/4" x 5-1/2" pen blanks or 1-1/2" x 1-1/2" x 1-3/4" bottle stoppers.
