The large spherical heads on these beaters are made from medium red rubber. They are hard enough to produce a loud bright tone with long decay, but the rubber has a small amount of give that negates the contact "click" one might expect to hear from a more attacking solid plastic or wood head. This bounce makes these beaters particularly good for middle-pitched resonant tuned percussion instruments such as metallophones and chime bars.
Each head is mounted on a tapered black plastic shaft with Easy Grip handle. This addition increases control and makes the stick easier for inexperienced or disabled percussionists to hold.
