Febreze カー用ベントクリップ リネン＆スカイ エアフレッシュナー (20個入り)

The clip is super discreet and doesn't block the vents at all, plus the light scent isn't overpowering like some other air fresheners. I've had one in my car for over three weeks now and it still smells fresh.

I was skeptical if these would actually eliminate odors, but they really do—my car smells fresh even after a week of fast-food runs. The fact that a single clip lasts up to 30 days on low is perfect for not having to remember to swap them out constantly.

The clip is surprisingly discreet, it doesn’t block the vent at all. I popped one in before a road trip and the linen scent lasted the whole drive without being overpowering. For twenty clips at this price, it’s a solid deal for keeping the car fresh.
