Slotted tungsten beads will fit around the 90 and 60 degree jig hooks. The slot also allows you to put a normally undersized bead onto a large hook (as in the case of a 1/8" or 5/32" bead on a size 6 or 4 egg pattern). These beads tend to be a little heavier than countersunk beads. 20 beads per pack.
