The Field Series FS550 hard plastic xylophone mallets are hand-crafted from quality materials that make them ideal for field percussion. The FS550 weighs more than other mallets in Innovative Percussion series, providing for better projection on an open field. These mallets are identical to the FS550R, but the FS550 features polished birch handles. The attention to details, superb sound, and strength of the Field Series mallets makes them a necessity for on-field ensembles.
