One pouch of four Little Trees Black Ice Vent Wraps. Black Ice is a mysteriously enticing cologne-type fragrance with notes of citrus and cedarwood. Vent Wrap is a slim Little Trees car air freshener that slides onto a blade of the air vent. It blends into the dashboard, lets air flow freely and spreads a steady, consistent fragrance through the cabin. Each Vent Wrap gives up to 20 days of fragrance, so one pouch of four gives up to 80 days. The wraps come in a resealable stay-fresh pouch that keeps the unused ones sealed until you need them. The fragrance meets or exceeds the International Fragrance Association guidelines and the product is made in the USA.
