The pro modeler series of kits are from Revell-Monogram... with that said, I can't wait to see what you do with yours.. I have a few of these amt "new tool" '57 chevy kits including Coke edition version...
If the tip dries out, you could pull it out of the pen and drop it in jar of clean lacquer thinner to clean it and set it out to dry.... Then re insert it in the pen and your good to go again... I think..?
