Queso, Those are real nice pens, you did a great job... However, IMHO, you are underpricing yourself...
If I were to make those pens from a Baron kit ,TN Gold $25 or Upgrade Gold $16 for both kits, I would charge around $150 shipped in a wood box... especially for a unique material like corn cob, I know what kind of a bear it can be to produce a quality pen from one...
Again, this is only my opinion, I think the Baron or the Jr Gent would be a lot nicer looking kit also... I personally do not care for the PSI kits I have seen and used... I don't care for their plating... I have found that the Berea and CSU kits ,again IMHP, have superior plating...
My basic cigar pens are $50, my cob cigars are $60.00 without a wood box, my Baron and Jr Gents start at $65 and go up from there depending on plating and materials used, they are sold in a clear plastic box.. These prices are what I get at my local farm market crafting booth...
Now I live in Western MD farm country and can sell at these prices... you are in a lot more affluent area than I am... you should be able to get a bit more...
Again, I am not trying to tell you your business.. but you seem to be on the edge about whether this is a profitable thing to continue... it can be if you charge enough and use the right kits...
