one of the best scents but fades fast [SEP] i bought a used car and the dealer used these he could not remember the name so i searched high and low for them i was glad to find them on amazon they have a great scent i have gotten a lot of compliments with black ice sapphire my only complaint is that they fade quickly i usually have to place several bars in the car before i smell anything and it all but fades within days so a bag of might not last as long as one might expect
