Everlast HDPE pen blank mold casting system bundle by Penn State Industries. Includes a 2 chamber mold, 4 sets of silicone tube mounts and 2 silicone stops plus mold release and brush.
Just mix colors or materials into your resin, pour the resin into the mold and allow it to cure. These tough 2 chamber molds are precision-milled in the USA from blocks of HDPE (High Density Polyethylene) so they won't warp or crack. They are non-stick and easy to de-mold and are 100% sealed against leaks.
Will cast two full length blanks up to 5-1/4" long by 7/8" square as well as decorated tube-in casts. Includes silicone supports for tubes of virtually any diameter or length. Silicone stops are supplied so you can pour shorter blanks (using less resin). Compatible with casting resin like Alumilite; works with or without a pressure pot but you must use a release agent due to the rigidity of the molds.
Price per bundle in Canadian dollars.
