Bug Collars are a great way to add extra weight to Bug/Nymph patterns. Painted in Fl Chartreuse, Fl Orange and Fl Pink, they can also act as a hotspot on the fly. First, place a standard countersunk bead on your hook, then slot on a Bug-Collar. It will fit snugly into the recess on the bead head. 20x per pack (2.8mm brass).
