Air Freshener Black Ice Crosshair. Black Ice fragrance oil is a bold, clean, and mysteriously enticing masculine scent. It features a crisp burst of icy citrus and eucalyptus, mellowed by a refreshing floral heart, and grounded by a rich, smooth finish of warm woods, ambergris, and musk. The Air Freshener is made with fragrance and colored Polymer beads baked in a mold and hand painted with acrylic paint. A small eye screw and hemp cord makes hanging the Air Freshener over a rear-view mirror easy and convenient.
