This item was used. I wiped off the dirt, but it wouldn't come off, so it remains in this condition. It's clay residue. It might come off if you scrub it with detergent. The back reflects light, making it difficult to see in the image, but there are scratches and dullness. Please check the images and understand the condition before purchasing. Please refrain from purchasing if you are concerned about minor details. I will ship it out the same day. Production mat Clay mat Cutter mat Cutting board Clay board
