These unique pens were created from hand-cast Jesmonite blanks, then turned on a lathe. The stunning marbling effect was achieved by incorporating colour dye during the casting process. Jesmonite is a material not normally seen in pens or indeed turned on a lathe at all. Considerable time was invested in refining the casting and curing techniques to master how Jesmonite can best be turned.  The result is a pen with amazing colour depth and a pleasingly healthy weight that distinguishes it from standard resin, acrylic, or wooden pens.
