600mm (2 foot) x 600mm x 40mm - Lightweight polystyrene terrain tile. Each tile features a 20mm deep embankment (to water surface) T-Junction river section with textured mud and grass embankments. The river bed features various areas of mud and rock bedding. The river has various grey-blue shades for an authentic river effect. The river section starts and finishes centrally on the tile edges to allow for sympathetic "joining" to other river sections. Each of these boards can be used in conjunction with the various other tiles in the range.
