You get 7 Harps. I got mine on sale, so can't complain. They wear out fast, though. Still, as the other user said, great case. And the harps are not all that bad. Just keep 'em clean, and they'll last a while. I've had mine going on 10 years now, and they're still all functional, so I mean, that's pretty good.
The quality of these harmonicas is pretty low. However, it is a great case worth the price anyway. Also, now have a couple extra harmonicas in keys I would have never bought, so let me try some new stuff.
