The PM 451 is the smallest beater among the plastic-handled mallets. It is 255 millimeters long, and the hard felt head is 25 millimeters in diameter. The PM 451 is very light, robust and easy to clean. Areas of application are, for example, toms and mallet instruments. The PM 451 can also be an alternative for hard mallets with wooden heads. The stroke sounds more damped, therefore this mallet is also used for singing bowls.
