River Expansion: Bends contains three river sections; a sharp bend section, a tight bend section and a curve section. Included with the pre-painted rivers is a small bag of Green Static Grass allowing you can flock the river banks to match your battlefield, or you may wish to use one of GF9’s many other Hobby Scenics to blend the piece in seamlessly with your own terrain collection and models. These pieces are cast in a flexible material to withstand the rigors of gaming.
