The Rohema Shake Me shaker is made of high quality brass and natural wood, filled with steel sand. Depending on the pitch, the grain of the filling is sometimes finer, sometimes coarser. In addition, the tone color is already recognizable from the wood used. For the light sounding shaker we use light Beech, for the warm, medium pitch we use Jatoba and for the dark sounding shaker we use Walnut. The set of 12 contains four shakers of each tone color.
