These rivers work great with almost any scale, they can be used as streams or narrow rivers for larger scales (15/20/28mm) or can be used for full-fledged rivers for smaller scales (6/10/12mm). They are completely finished and ready for the tabletop.
These rivers are approx. 1.75 inches in width with the overall piece (including river banks) approx. 2.5 inches wide. The photo above shows the river in use with 15mm figures.
