Mostly cat's eyes. A few Masters maybe? I don't see any handmades.
The most interesting ones to me are the clear with the white ribbons on the edges which probably are Vitro cat's eyes, but it's an interesting construction. If there are 8 ribbons there, then that might be special.
Soooo .... yes, some people would probably call it slingshot ammo. Except the possible 8-ribbons cats.
$15?
