In the USA, manufacturers vary in quality and consistency. The same is true in China. Some have excellent quality control, and will produce exactly what the customer wants. Others have virtually no quality control, and punch out quantity on a budget. Some diligent folks in the USA have done their homework for the rest of us. They have put together a collection of quality lure blanks. Often they pay to have special molds made to get exactly what we want. They require higher standards from the manufacturers, and get better results. It seems to me that $2 vs $.70 is a small price to pay.
