The Odyssey septum clickers feature 5 hand-set synthetic opals and have a wearable length of 1/4″. You can also choose wearable lengths of either 1/4″, 5/16″ or 3/8″. Wearable length refers to the distance between the post and the bottom of the clicker. This septum clicker is manufactured by Industrial Strength using 6AL4V ELI ASTM F-136 implant grade titanium. If you require larger than a 12 gauge, you can choose one of Industrial Strength’s Clicker Gauge Adapters which will fit on these 14 gauge clickers.
