Details After years of research Malletech were able to find a way to keep the weight of the four models within one-tenth of an ounce of one another. The Natural Rubber Series by Malletech is useful on marimba, small bells, wood blocks and other idiophones of the percussion section. These Natural Rubber Series mallets feature birch handles of the same length and diameter as the Malletech marimba mallets. 1-1/8 inch diameter heads.
