Febreze Unstopables Auto Luchtverfrisser Geurverwijderaar, Shimmer, 2 Stuks

Finally got these for my car and the shimmer scent actually makes a noticeable difference even with the AC on low. The tiny clip design doesn't block the vent at all which I was worried about.

I popped one of these into the vent before a long road trip, and the scent lasted the whole three hours without fading. The clip itself is tiny and discreet, so it doesn't block the airflow.

My commute is way more pleasant now—these little clips pump out a steady, clean scent that actually makes the car smell fresh, not just covered up. The scent lasts a good few weeks even with the vent on high.
