The expandable wick absorbs and holds twice the amount of scent as most wicks. Acting like a sponge dipping the expandable wick in a scent it will swell to capture more scent for a long lasting and more effective hunt. The Expandable Wicks design allows for ease of dipping right into a bottle of scent.
