These are really cool! Carbon fibre cable housing ferrules!
The walls have to be thicker than metal to assure strength so they have to be of a longer, stepped design, which means they’re bigger, longer and
heavier as well as more expensive.
So it appears their only reason for existing is “cool factor”.
Sooooooo stoopid!
And now to throw them out... and you can’t even recycle this crap!
