Vandoren V12 Clarinet Reeds, Strength 3, Pack of 10 - Brand: Vandoren - Model: V12 - Size: 3 - Quantity: Pack of 10 Thank you for viewing. I purchased these as reeds for a new mouthpiece, but I returned the mouthpiece and no longer have a use for these reeds, so I am selling them. I took them out of the bag, but they have never been used.
