Why choose Cooks? Their products are collected fresh, just prior to shipment from their own cwd free certified deer herd. None of the scents are carried over from the previous year. Scents are collected from early fall and through the rut not in the spring and summer months and shipped directly to the customers. Their scent is 100% pure, fresh whitetail deer scent, no water or preservatives added. All hand bottled and tested (organoleptic) for freshness by their quality assurance staff. The scent is bottled using pharmaceutical grade bottles that are amber in color to keep out light and have sealed caps to prevent spillage. No sitting on store shelves for months prior to use. You’ll see the results!
