These bright blue trade beads are part of a uniform strand measuring about 28 inches in length. The beads are mostly the same size, averaging about 12 mm long with a diameter of 7 mm. They all have a yellow diagonal stripe with a red line running through it. Note: Some of the beads on this strand have very tiny -- almost pinhole size -- white holes embedded in the glass. They apparently are a part of the glass from when it was originally made.
