Manufacturing Tolerance and Variations:

Please note that due to the inherent manufacturing process, there may be slight tolerances +/-3mm in the size of the bricks. Similarly, subtle colour variations may occur between bricks, which does not affect the product's performance. It is also normal to find small chips on the bricks; this is not a product fault but rather a characteristic of the fire clay brick. These can be easily covered by Mortar or Cement, if required.
