They took the most powerful liquid deer attractant ever and developed a patented solid stick formula that encapsulates and protects the estrus pheromones until it is applied. When applied the pheromones are released by evaporation. The advantages are: ease of application, re-sealable container, no spilling or leaking, will not freeze and will not break down in temperatures under 100 degrees. Can be stored safely in a hunters backpack. The stick is recommended to be used on their scent sponges and stored in a ziploc bag between uses. This Patented stick formula will change the scent industry forever.
