In its pure form, I would guess that this statement would be true - then that would lead me to believe that these clips are made of pure 6-6...and there I have my doubts. I'd be looking at the molder, and/or the 're-work' that goes into making this piece of plastic - not the 6-6. A former Plastics guy, Rook
