Paulcomi, I don't believe you got an exact answer to your question. The guys use HDPE (High Density PolyEthelene) for building the jigs. Another good choice is UHMW (Ultra High Molecular Weight).

BJ, not having the chance to see before you buy is always risky. Having looked at the bags I can tell you that some are real values and others are many small pieces only suitable for spacer applications. I would avoid this type of purchase unless you are buying in person and see what you are getting.
