This combo pack contains three Big Dipper Scent Wicks and one Seal-Tite Scent Wick Container. We have now placed an orange reflective band around the wicks. This will make the wicks easier to locate when the sun goes down. Our wicks also have a larger hang hole along with two tails that can be easily dipped into any scent bottle. The wicks are made of a non-reactive synthetic felt. The new, slimmer design container provides the hunter with a way to store and transport there scent wicks. It also provides a way to get to and from their hunting area without releasing scent.
