These rivers work great with almost any scale, they can be used as streams or rivers for larger scales (15/20/28mm) or can be used for wide rivers for smaller scales (6/10/12mm). They are completely finished and ready for the tabletop.
These rivers are approx. 3 inches in width with the overall piece (including river banks) just under 4 inches wide. The photo above shows the river in use with 20mm (1/72nd scale) figures.
