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.
