These flexible silicone molds let you create your own custom pen blanks by pouring in resin mixed with whatever colorants you like. The mold includes two cavities for pens, plus 8 stoppers with cones that center your pen tubes inside the castings. This means there is no need to drill the pen blanks after curing. The stoppers can be adjusted to accept brass tubes up to 7'' long and 0.175'' to 0.5'' in diameter. If you want to create blanks without tubes, use the flat sides of the stoppers. Once cured, the flexible silicone makes it easy to extract the pen blanks. Creates 3/4'' x 3/4'' blanks.


  • Both mold and stoppers are made with silicone for easy release once cured. To prevent damage to the mold and prolong its life, we strongly recommend using Stoner Mold Release (66406, sold separately)
  • Cones on stoppers center pen tubes in the cast blanks and can be shifted to fit brass tubes up to 7'' long
  • Use flat sides of stoppers to make blanks without tubes
  • Stoppers fit tube sizes from 0.175'' to 0.5'' in diameter and fit tightly in mold to contain resin
  • Lines in mold cavities mark optimal fill height of 3/4''; inch scale on top provides reference
  • Ribs on outside of mold prevent bending under weight of resin
  • Matte exterior for easy removal of excess resin; high-gloss interior leaves smooth finish
