These are an unusual shape of glass beads. They are like a rondelle but offset to one side. The shape looks like a hobo bag with a narrow end and a larger rounded end. They push together to make a squiggly strand of beads. No other beads have been found on the internet like these.
As can be seen in the photos above, vibrant cobalt blue color peaks out from inside the clear glass beads.
There are 50 beads in this strand.
Photos above are a fair representation of the actual beads.
