Cowboy Series - Silicone Mold

$ 30.00

BUNDLE AND SAVE: Cowboy Series Special includes the series mold and initial stoppers, 4 universal small stoppers and 4 tube-in small stoppers, and 6 label sizing templates associated with the mold. $45.50 (you save $6.20)

This blue tube-in silicone mold casts one upper and one lower tube for the following kits:

  • PSI Cowboy Twist Pen Kit
  • PSI Skull Twist Pen Kit
  • PSI Dragon Twist Pen Kit


COWBOY TUBE-IN SMALL: If you are casting the Cowboy pen kit with this mold, you will need the longer tube-in small stopper sets. 

COWBOY UNIVERSAL SMALL: If you are casting either the Skull or Dragon pen kits with this mold, you will need the shorter universal small stopper sets. 

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.


      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.
