3-pack of strike indicators on a paperboard card

Buoyant enough to float a size 14 nymph with 2.8mm tungsten bead head, plus a size 18-20 dropper, depending on conditions and rigging. 

Easier to use than foam stick-on indicators or other indicators with external attachment hardware

Oros indicators feature patent pending Soft-Lock™ technology. The design encloses fastening hardware inside of two molded soft foam hemispheres. When closed, the hardware holds the line, while the foam hemispheres compress creating friction between the two hemispheres that keeps them from disengaging.
