The small 1 oz spray can is portable and discreet so you can throw it in your bag and have it with you anywhere you need it. It's also made in the USA and 100% safe for hair and clothes, so you don't have to worry about particularly aiming it in any direction other than where the odor is strongest. Plus, just one spray is enough to freshen a normal size room, so you'll get plenty of use out of even just a single can.
