These natural beauties are the perfect accessory for everyone's car. They are hand-filled with woodsy herbs and infused with the same essential oils to enhance their air freshening powers. They smell like you are riding around with a tiny bit of the PNW forests that we love so much. Use the cotton string attached to hang from your rearview mirror and let the sun warm it up for best results. Give it a squeeze every once in a while to release its scent even more. Each car freshener cotton pouch is filled with our proprietary blend of natural herbs and essential oils. You can choose to mix your case of 12 with 6 of each design, or all one design. I package the car fresheners in plastic bags with the label on top for my stockists, but am all about saving the planet from plastic, and have a plastic free option as well!
