2 Blank Adjustable Horizontal Mold Bundle w/ Starter Replacement Stoppers

Original price $ 54.95
Current price $ 49.95

This silicone mold casts up to two square blanks at a time. The mold has unique voids different from our other horizontal blank molds that can be easily improvised as an adjustable tube-in casting system. Included in this package offer are the four of the stopper replacements that can be screwed to the enclosed stopper holders for the selected pen tube you want to cast.  

This bundle defaults the original four set of stoppers (universal slimline, universal small, medium, and large) and a Tube-in rolling jig to help with applying the labels. A great trial opportunity for casting beginners just starting out before they invest in our dedicated pen kit mold designs. Please contact us for more info or if you would like another stopper combination!
