Thank you for viewing! D'Addario Reserve Classic B♭ Clarinet Reeds Strength: 3.5 + 7 reeds I've played them to test the sound. I'm selling these because the strength didn't suit me. They will be placed in the included paper case, and the box will be folded and included. They have been disinfected, but please understand and acknowledge that they have been tested. I will strive for courteous and prompt service (*^*)
