Get the most out of your scent! Most companies do nothing more than offer a rectangular piece of felt with a small hang hole at the top. The HME Products Reflective Vent Wick has features that set apart from the competition. For starters, HME has added six 1/4'' vent holes. This will allow more air to pass by and through the applied scent providing a stronger scent dispersal. We also made the hang hole larger making them easier to hang. They also include 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. Sold in a resealable bag.
