Recorder Mutes

These are a life saver (hearing saver!) for the elementary music teacher.  This simple device will significantly cut down the sound volume of the recorder.  That one kid in back playing as loud as he/she can on purpose? Solved. 

In addition to the muting feature, the mute will force students to use the appropriate amount of air.  Over blowing will result in no sound.  The proper amount of air results in a quiet recorder sound. 

These come in a pack of 40 mutes, which is enough for a classroom set plus spares.
