We imagine that these might be the skull of the devil or diablo skull beads because they are red - red plastic that is. They are accented with black to highlight the features - eye sockets, teeth and nose. Each bead features a large stringing hole that goes from top to bottom.
The bead measures about 3/8 inch high by 1/4 inch wide and about 3/8 inch from front to back.
Although these are made of plastic, they seem to be made of something much nicer, so you can mix these with other beads on a special necklace or bracelet and be pleased with the result.
We're showing you two beads so that you might see them from different angles.
