Get the most out of your scent! The HME Reflective Vent Wick has features that set their heads above the compitition. It has 1/4" vent holes, allowing for more air to pass through providing a stronger scent dispersal. The hole is larger to make it easier to hang from branches. Also includes HME's signature reflective band so they are easier to locate as the sun goes down. They are made of a non-reactive synthetic felt. 8 per pack.
