Premium car air freshener that is ideal for placement under the seat in your car. Freshens and deodorizes with natural fragrances. Classic Japanese style, a must for any JDM vehicle! Made with water-based gel, so make sure not to open the whole thing at once, or it'll dry too quickly! We recommend opening it 1/5th at a time (every week to two) and placing it under the seat away from the sun. When done right, the Fresh Box indeed lasts up to 60 days or beyond! Non-refillable.
