The Rohema Shake Me Shaker is made of high quality brass and natural wood. The Shake Me is filled with steel sand. Depending on the pitch, the grain of the filling is sometimes finer, sometimes coarser. In addition, the timbre is also already recognizable from the wood used. For the bright sounding shaker we use light beech, for the warm, medium pitch we use Jatoba and for the dark sounding shaker we use oiled beech wood. The set of 3 contains one shaker of each timbre.
