HIRST ARTS MOLD #63 - OCTAGON TOWER   - "Will make blocks to build a 5" wide octagon tower (measured outside from flat to flat). Additional basic blocks are needed to build the tower. It includes a new style of arrow slit, brick edged window arches and trim pieces." Skullcrafts only uses gray Merlins Magic to produce top quality castings of Hirst Arts molds. Great care goes into each and every cast to ensure that all bricks are bubble free and all the same sizes. Alternately, you can directly buy Mold #63 from Hirst Arts to cast your own octagon tower blocks and order Merlins Magic from Clint Sales and Mfg. Skullcrafts is a fully licensed legal seller of Hirst Arts casts, kits and assembled & painted pieces.
