Alto Saxophone Soundproof Bag Silent Case EL-SAXCO (Made in Italy) I used this because I wanted to slightly reduce the sound that echoes to the upper floors of my apartment. I am selling it because my practice environment has changed. ■ As a bonus, I will include aftermarket high-density urethane sound-absorbing material, so you may be able to slightly increase the soundproofing effect depending on how you use it. ■ There is some wear and tear, but I did not see any noticeable stains or fraying. #AltoSaxophone #Saxophone #Mute #SoundAbsorber #Soundproofing #SaxophoneMute
