This item may be a little strange to post here, but I am doing it anyways. I have two spools of carbon fiber thread. The first is a 2lb spool if 12k thread. It is in shrinkwrap and has not been opened or tampered with. The other spool is in the same condition but is (I think) 6k or 8k thread, in shrinkwrap. The manufacturer is Thornel by Ammoco carbon fibers, which is now Cytec. I live near the plant in SC where they are made and all of it is extremely high quality. I will consider all offers, and they do not include shipping. I will check this thread periodically. Thanks for your interest.
