Little Trees are the classic hanging cardboard air fresheners for cars, made by Car-Freshner. Each tree is made of absorbent paperboard infused with fragrance that is released slowly over time. This is the Frosted Pine fragrance, a fresh pine scent. To use it, cut the top of the bag, pull the elastic string through and hang the tree from the rear-view mirror or a hook, then pull the tree out of the bag a little at a time; exposing it gradually controls the strength of the scent and makes it last longer. Little Trees also work well in wardrobes, cupboards, caravans and small offices. This listing is for a single tree.
