Deer use their sense of smell as their primary communication method with other deer. These scents come from 3 primary glands: Preorbital, forehead, and interdigital. Buckstik has developed a line of all three glands that are 100% pure and 100% natural. Processed in a laboratory setting to ensure purity and consistency these highly coveted glands have an unlimited shelf life, low evaporation rate, and unlike urines have no usage restrictions. A VERY powerful attractant, just one or two sprays are all that are needed to bring in dominant bucks. The Large Gland kit features three 10 ml spray bottles: #1 Preorbital Gland #2 Forehead Gland #3 Interdigital Gland Ideal for Buckstik or BuckBranch Users. This is the larger 10ml bottle kit. If used properly, this kit will last over 4 seasons per BuckStik. Check out the "Glands" Tab for more information.
