I'm a relatively new sax player and I've been trying out different reeds to find one that I like, so I've been buying singles from local music stores. I bought a couple of Vandoren ZZ reeds, but they didn't come in individually wrapped packages like the blue and green reeds (which I've also tried). Also, looking at the reed holder, it looks different than the other ones I have. (Corners aren't rounded.) Anyway, I'm just wondering if I'm using the real thing.
