12 Heavy Engineering Bricks - Fire Bricks - Ballast Weights.

Size approximately 9.0 x 7.5 x 1.5 inches, plus a 0.5 inch flange on each side. Very heavy. Ideal for holding a tent or gazebo down, or as ballast weights. No idea what they were used for - maybe storage heater bricks. I dug them up in my garden.

DON’T EVEN THINK ABOUT ASKING ME TO POST THEM. They are for collection only.
