Mold & Pen Style References -- Will it FIT?
A reference list for the various Designs in the Store and compatible pens can be found in the More drop down menu. The important item is the tube size. If you have a style with a very similar tube dimension, it should fit the mold. A little longer tube will reduce the slack space in the ends of the mold.
I will add more pen style references as the site progresses and molds are added.
