This little ceramic skull bead could definitely what you need for tiny ofrenda for The Day of the Dead or Hallowe'en. The shape of the skull has been accented with hand painted detail lines, but as the generous hole goes from side to side, you can easily glue it into an assemblage. And, it is certainly perfect for earrings and bracelets.
The bead is about 7/16 inch wide by 3/4 inch high. The stringing hole is not quite 4mm in diameter.
