Similar to the one-time cast 3D style printed molds, our outer shells are cast from Alumilite Clear resin using our own color mica powders, or we can combine with pigments or dyes available at PTownSubbie.com. To finish the pen blank, you cast pours in each void to create an all resin gisi style (arrow / chevron) pattern.
These shells are custom cast to order. This order will create an outer shell sized for the sierra pen kit. Please contact us with your option and choice of colors if not listed as a variant.
