These are 4mm acrylic plastic bicone beads. There are two colors in this listing - 30 translucent light blue (sky blue; not shown in closeup) and 31 shiny solid light blue (baby blue).
The pictures show the exact beads and packaging you will receive. One has closeups of the beads for better viewing of the color and quality. I apologize for the size of the pictures, they are small beads and difficult to photograph.
