Possible production of Munchkin Card Shoe

I have a friend with a laser cutter, and I have piqued his interest by suggesting there is profit to be made on these shoes. We are still in the very early stages of negotiation and pre-production, but if the materials and labor are reasonable I will be looking for a way to buy thin cardboard boxes, and then attempting to sell these bad boys. Honestly, I am excited. I don't expect them to make me rich, but it would be nice to make a little scratch from a hobby item.
