Classic vintage colors and shape!
These beads are a little different. The two larger beads are twisted ovals. The small bead is sort of a square, but the edges are on the diagonal, allowing them to nest when strung together. Very interesting, unique beads.
I wish I could remember by geometry, because I'm sure there's a name for this shape.
The large bead is 12mm, the middle bead is 8mm, and the small beads are 5mm.
The largest bead is 11.75 for 12, the middle is 11.75 for 20, and the small beads are 11.75 for 40.
