considering mass fabricating fiberglass "shark tooth" duster grills

I CALL BULLSHIT!. just to set up a unit to make them and a mold, all the other crap involved, there is no way in hell you could sell them at 75 bucks!, unless you bought 1 million from them up front. i use to deal with a guy that did patents, and it costs like 80k for seting up a machine just to make some of the stupidest toys out there with no itriquite parts. A GRILL, FORGETABOUTIT!!!!!!!!!!!!!!!!!!
