Fire brick for sale in Bakersville, NC

Here are the details from János Herr:

K-23 (2300 F) Insulating Fire Brick: 9" x 4.5" x 4.04 x 2.5"
Regular price $5-$5.25 selling it $3/ea.
These are so-called key bricks; one end is slightly smaller than the other (see dimensions above). You can still use it as regular even sided bricks. I have 35 boxes of 25, 875 bricks all together.
