seriously, if u open a business based on the theory that charcoal can clean the air in your ride-using this principle and create a nice bottle say a replica of r33 or s15 or fd3s , which is made in China,and later sell it around rm10, dont u think u can make some bucks from it?
Many men, which i know, and which own a car, put ambipur( the rm12.00 one) inside their car because the bottle is so practical and the semll is nice.but so far never see charcoal perfume yet.
