A set of ceramic firing supports and dice in various sizes. - Quantity: 4 types of supports x 4 each, 4 blocks - Sizes: Height 15cm, 10.5cm, 9cm, 6.5cm - Dice: 4x4x4.7cm (3 pieces) 4x3x2cm (1 piece) Used for about 10 years. There are burn marks from firing, but I don't think there will be any problems for future firings. Thank you for looking.
