These are premium skull beads. They are a higher quality version of the common skull beads that are used on para-cord lanyards. These are Translucent Grey in color. We call this model "Lord Greystone". Each one has a top-to-bottom hole design of 4mm width and is made from ABS. These are light weight and will not scratch your knife or other object.
These are very rare!
