The Rohema Poly Rods are designed for subtle, quieter sound. The rods are made of extremely resilient polymer fibers that produce a clear, distinct sound. They have more volume and less weight than wooden rods. The handle of the Poly Rods is coated with rubber, providing plenty of grip and comfortable handling. The Poly Rods have a diameter of 15 millimeters and are 400 millimeters long. With two flexible adjustable rubber rings, the sound of the rods is individually adjustable.
