Osilly 5PCS Hanging Car Air Freshener, 8 ml Oil Diffuser Perfume Aromatherapy Pendant Empty Glass Bottle, Fragrance Ornament with Vent Clip Wooden Cap and Rope, Auto Interior Decoration (Cylindric)

These are great. A few ml of your favorite essential oil, and you have an awesome car air freshener. My favorite is to add cherry almond. The heat from being in the car helps the scent to permeate and every couple days I just tip it over and get the wood top wet with oil from The inside. It’s enough to help the scent spread even more.

Easily fill up these bottles with your own scents and they work great. I actually crocheted a small hanging plant and place on of these inside so it smells great and looks good too

Works great, but hard to fill with scent of course due to neck size.

At first I couldn't figure out why I had to get so many of these little bottles, but once I realized the oil works it's way up the strings and the wood bead so you can't mix oils, I realized what a deal this was. I still haven't had to fill my first bottle which I filled end of March and my car smells amazing every time I get in it. Easy to refill and attach to the mirror (just tie a regular knot once you're ready). Can't wait to use another one of my oils when this one is gone!

It’s hard to tell if the item produces the scent I’ve chosen.

Awesome price for this many! Easy to hang in your car and refill with your scent as needed. Great alternative to synthetic air fresheners. I’ve seen boutiques selling these exact ones filled with their scents for high prices! Just turn the bottle over every few days to release more scent.

very easy to fill with a small funnel

I was tired of using chemical smells in my car. Therefore, I decided to use natural oil, and these bottles were exactly what I needed. Of course, I need only one, but I bought the pack because I think it is also a perfect gift for friends. I would like to maybe have more color options, but it does not really bother me. Perfect price for perfect quality.
