This is my own invention, they are manufactured in the USA and assembled right here in Tenerife! This get's banned every time I try and post pictures on the weightweenies forum, so I decided to present it here instead.
They are manufactured from high-purity alumina. Each piece is very strong & stiff... overall, the segmented design means that they are super flexible. They are also will never corrode like aluminium nokons. I have probably sold about 10-12 sets so far. The current price for a set of ceramic gear lines is listed as US$140, but that is likely to increase next month.
