This is the second time we have had Fordite Blanks (also known as Detroit or Motor City agate) as they are incredibly rare! These blanks are believed to be from a Hyundai plant and are extremely cool!
Fordite is a buildup of old automotive paint which has been baked numerous times and hardened sufficiently to be cut and polished.
They are sized at 3/4 x 3/4 x 5".
*Recommend using solid carbide to drill.
