And it wasn't made by your average reed carver, either. This reed was made by none other than the magical reed-carving hamsters that live under the floor of the band room. Have you ever heard a scratching or squeaking noise in a recording of your band? Conductors will tell you it's just a clarinet, but since clarinetists are PERFECT they would never make a mistake like that. They know it's really the reed hampsters. The hampsters learned the art of reed-carving a long time ago, which is why today they all seem obsessed with chomping paper towel rolls into tiny, tiny pieces with their little teeth. The magic reed hampsters can carve reeds for you if you find the opening in the floor where they come and go, and ask them nicely in reed-hampster-language. Just don't mention birds, because birds are always trying to steal their reeds to make nests.
So here's how it works: the reed will always sound good, no matter how many times you use it. It's guaranteed (by the hampsters) to last until the internet explodes. And even then, there are ways to save it. But take good care of it, because I don't know if I'll ever be able to get you another one--getting to Symphonia ain't easy, y'know, especially with those huge conductor-dragons guarding the enchanted plain...
