are they actually self-lubricating like Graph Tech?
Q: What is the material made of?
A: The proprietary and unique material formulation of our nut
is high-:pressure injection molded to create a brighter, tusk-like
tone while producing slip lubrication properties superior to
graphite. Get the best of both-have a bright bone sound with
slip properties superior to graphite!
I think it just says its slippier that graphite, could be wrong.
anyone who uses them?
Not sure, google it.
