This is a hand machined bead made from 1.125" diameter piece of grade 5 titanium with a 1/2" diameter Zirc cap. The cord is held in place with a set screw within the cap and the then thru the body of the bead. This bead is 1 3/8" long including the cap. I have installed a 60" long piece of blue/black 550 cord, giving the bead two 30" tails. 

The price listed is per bead, these are not sold as a Begleri set.
