Most tube-in series are universal in nature, if the tube length is close and bushings are the same size or smaller, then the tube-in blank should cast properly.  Please visit IAP Kit Bushing and Tube Reference for various pen kit dimensions.

                  Initial set of stoppers are included with a mold purchase. CLICK HERE to buy replacements.

                  PLEASE NOTE:

                  Blue molds except Gisi Style Molds cast Polyester Resin (Silmar 41), Urethane Resin (Alumilite Clear), and Epoxy Resin.

                  Mold release sprays help to extend the shelf life of our molds. We recommend Stoner Thermoset for Polyester and Epoxy Resins, and Stoner Urethane for Urethane Resin.

                  Please contact us or visit our Casting Basics Guide for more information on mold casting.
