The Loon Easy Dry Fly Treatment provide moisture wicking beads for reviving tired, soggy flies. The treatment to revive flies is composed of two things: drying beads and blue indicator crystals. A fly (still attached to the leader) is dry after a few quick shakes and ready for floatant. 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.FeaturesDrying agentBlue indicator beads turn pink when it's time to replaceEasy to use shake applicationLarge cap opening for any size fly
