These sheets are invaluable for scratchbuilding, saving many hours of repetitive work creating the various surface patterns and textures. They are the same as those used in the Craftsman kits to make extension work easier. Each pack contains 4 sheets 170mm x 113mm of injection moulded styrene and thin enough to be sufficiently flexible to form the underside of a viaduct arch.
