I am so used to seeing perfectly round pop beads....and they are always 1950s. I have never seen this color combo. They have a little bit of a sheen to them. And the sheen is some sort of overcoating because they feel like a smooth molded plastic but one bead has a little bit of that coating missing in a small spot near the "pop".
So look at exhibit #2....
(they are not QUITE as shiney as the scanner made them..they are more a soft pearlized sheen than harsh metallic)
