It's been a while since I got the ones I ordered. Lots of big, and I mean big, flints, some the right size, some pieces that just happened to fit in Large Silers, and a few easily used as-is or broke to the right size. I still have most of them left and what I've used so far seemed to work just fine. Quite a few were amber flints and most were dark flints. I'd say it was worth it.
