Review on 🌸 Car Air Freshener: Floral Scent Crystal Gel with Natural Plant Extracts for Refreshing Smell in Cars, Boats, RVs, and Pet Areas - 1 Pack by Tony Trotter

This is a box with crystal gel air freshener inside. The top is securely attached. My car hasn't been used much in the last year and a half so it's a bit musty. I followed the instructions and partially removed the foil. Even on a hot day, nothing happened until I completely removed the foil. At that moment, my car smelled really fresh. It is best to place it on a flat surface so that the gel does not spill out. I had it on the floor of my car and in the trunk. Works well in both places.
