Vandoren V12 Clarinet Reeds, Size 4, Pack of 10, with spare reeds. - Brand: Vandoren - Model: V12 - Size: 4 - Quantity: 10 reeds Thank you for viewing. I am selling these because size 4 was too hard for me after I purchased them on Mercari. I only tried two reeds, but I couldn't play for even 3 minutes on each. They have been disinfected with alcohol.
