There are approximately 5000 of these lovely cornflower blue glass beads in their original cardboard box.
On the box is a label stating MADE IN CZECHOSLOVAKIA.
They are 5mm wide with a hole that is aprox 2mm.
They are shiny and opaque.
The number on the box is 681.
I found these in an old warehouse in Malta and I think they may have originally been for lacemakers.
