Thanks for looking at these new old stock Paragon Ceramic Kiln replacement bricks. All of these bricks are in good condition but may show signs of storage. They have sat since a ceramics shop closed in the 1990's. I have a few different varieties available, so be sure to see if I have what you need! This brick option measures 9 inches long, is 4.5 inches tall, and 2.5 inches thick. Thanks again for looking!
