That's right, just $150 per wedge of the 1500 filament superconductor material. Photo is pretty much what you will receive. There are at least 2 rings in each piece with a good drill press and holesaw..... Diameters will be 2.5" on the round end and 3.8" at the oval. Average weight is 1.4lbs.
This is PREMIUM QUALITY superconductor from Copper444 with plenty of filament to work with.
