Nathan77,
After reading your posts about getting the sink rate to match Yamamotos, and seeing the pics of the baits you produce, I would not be afraid to ask between $6.00 - $7.00 for a pack of 10. That might even be too cheap. I don't make Senkos myself, so I don't know how much it takes to produce one. Your baits look very nice, so I wouldn't undercut myself on price.
