This product is a treatment used to dry off and revive dry flies. It has two components: drying beads and blue indicator crystals. Place any waterlogged dry fly, while still attached to the leader, directly into the wide mouthed bottle. Close the lid or put your thumb over the bottle's mouth and give it a few vigorous shakes. Your fly will come out dry and ready to apply a liquid/gel type floatant such as AQUEL. The blue indicator beads turn pink when the drying beads have become saturated and it is time to get a new bottle of Easy Dry.
