These modular fortification features are made using a light weight, strong, tough, durable polyurethane resin. The single features are designed to 'sit' on top of Hexon terrain boards or single hexes, but can be used independently. (Pieces fit into single hexes 100mm across flats.) The grey colour has been chosen to aid painting/finishing of the pieces. The entrance gate has the option of a gate, available separate, are free standing and cast from lead free pewter. The open gateway allows miniatures mounted on 40mm wide bases to pass through.
