The Mini NOS Bottle air vent freshener, 7.95. A blue billet aluminium bottle, 6.5 by 2 cm, that clips into a dashboard vent and holds a refillable scent.
A nitrous bottle for the dashboard
The bottle is machined aluminium in the shape of the real thing, scaled down to fit between two vent slats. The clip on the back holds it in the airflow, which is what spreads the scent around the cabin. When the scent goes, unscrew the bottle, put a fresh one in and carry on; the bottle itself does not wear out.
Size and colour
About 6.5 cm long and 2 cm in diameter, in blue. One photograph on the listing.
A small present
It is the kind of thing that gets bought for someone with a modified car, or by them for themselves at the checkout. It goes in a pocket and it goes in a stocking.
