small black Hebron beads, weathered and traumatized? They have a furnace-wound look to them, ruling out the usual African powder glass techniques. We can probably rule out the usual European suspects. The group they're in with and the stringing tell us nothing. The squarish cross section also hints at Hebron. Don't read too much into the "braided" appearance.

Otherwise, just some one-off strays from some low-tech industry. Not very pretty either and not enough of them to make an interesting bracelet or some such.
