I am working with an inventor of a small retail pin clip product. This pin clip is a retail product made of nickle coated 302 stainless steel wire .050 thickness that has two pin ends that need to be sharpened enough to pierce into light to medium weight fabric. I can provide drawings, tolerances and dimensions and prototype upon signed NDA. Our initial order is 500 pieces with high volume quantities expected after product launch. Inventor prefers this product made in the USA.
