Set of mutes for a drum kit. Works great cuts the overall sound in half. Barely used (used maybe 10 times) we tried it for my son but he wants it loud. Fits 12” 13” 14” and 16” tom and snare. 14” hi hat. 16” cymbal. 20” ride and 18-26” bass drum. Great for kids who are learning drums. We could have a conversation in the house while he’s playing with these on. They also protect your drum heads while you are practicing / learning. Paid $40 through sweetwater music.
