The Parma Violets Air Freshener brings the iconic sweet shop classic right into your car — that unmistakeable floral-violet scent that's been dividing opinion since 1953. If you're a fan of the sweet, you'll love this. If you think Parma Violets taste like soap, maybe try one of the others. Either way, it's a long-lasting freshener that actually fills the cabin rather than lasting three days and disappearing.

How to use: Hang from the rear-view mirror using the cord, or place in an enclosed space in the car (behind a seat, under a seat, in the footwell) for a slower, more subtle release. The scent release rate increases in warm conditions — on hot days the fragrance will be stronger. Remove the product from its wrapper fully for maximum scent output, or leave it partially wrapped to slow the release. Replace when the fragrance diminishes.
