While I was unable to track down any Hobbycrafts, Inc. that seemed to be associated with this pen, I did find this Tri-Chem documentation:
Tri-Chem´s artists produce many new designs each year that come as unique self shaded transfers, multiple use intricate stencils, preprinted pictures with exquisite designs and easy to follow step by step instructions to paint.
We also go to great lengths to provide many different painting techniques and ideas and all the easy to use accessories to make painting a real fun and simple task.
Tri-Chem is indeed a one stop shop for any one who ever desired to paint something beautiful but was afraid to. Millions of happy Tri-Chem users in the U.S. and over 50 countries have learned the simple Tri-Chem painting techniques in classes conducted by Tri-Chem trained Instructors. Classes are free.
