Three broken out of 24. The glass seemed very thin - paper thin - the tone of the unbroken bottles sounded OK compared to the high pitched tinkling of broken glass. It is possible that the shipping culled the flimsy bottles out and what was left was usable.I'm trying to figure out a way to test the 21 remaining bottles to avoid using a paper-thin flimsy bottle to store something important.
