I am seeking a company that can produce a Semi hard plastic product in florescent Orange color (My best guess is that a low density polyethylene would be a good choice. The colorant will likely need to have UV (ultraviolet light) stabilizer for use outdoors). We have a computer three dimensional design to scale of the product. We are seeking a company with the capabilities to obtain a lead product which will be six and one half inches long, one inch wide and nine thirty-seconds thick, semi rounded corners with a one eighth hole one half inch from one end to attach 75 feet of nylon cord. Approximately three thirty-seconds in diameter with approximately fifty pound strength. I am attaching jpeg files of the plastic design as well as 2 dimensional designs with dimensions and a third jpeg file of a current product on the market here in the USA to give you and idea of what the final product would look like.
