Clarinet reeds (strength 4). I usually use V12, but I accidentally bought V21, so I'm selling them. Four are unopened, and six are opened but unused. (I didn't realize it until partway through, as I was a bit out of it...) Like V12, they are lighter than Traditional, so they are also recommended for those who use Traditional 3.5+♪ Purchased February 2026 Vandoren / Vandoren / 3 1/2+
