Our Seasonal Glass Skull Car Air Freshener Diffusers bring limited-edition Birds of Valhalla scents to your rearview mirror — hand-mixed and hand-filled in our New York studio using premium American-made essential oils, phthalate-free fragrances, and a touch of eco-friendly glitter.
Unlike disposable fresheners that fade in days, our glass skull diffusers last 3+ months with proper use.
How to Use
Unscrew the wooden cap and remove the small plastic plug.
Add a few drops of fragrance to the inside of the wooden cap.
Reinsert the plug and screw the cap back on snugly.
Gently shake and hang from your rearview mirror.
Repeat when the scent fades to refresh.
Why isn't my skull completely full? This is intentional — every skull is filled to about ¾ (eye level) to allow for natural heat expansion. Not a defect!
Works beyond your car: Bathrooms, closets, home offices, lockers, RVs — anywhere you want long-lasting fragrance. Always keep upright; spilled oil can damage fabrics and surfaces.
⚠️ Random Set Note: Specific scent requests, exclusions, and allergy accommodations cannot be accepted for random sets.
📦 Subscription Note: Only the Single Random Seasonal variant is available for subscription.
I love them so much! I get the mystery pack, I'm indecisive and it's a little bit cheaper. I've loved them all so far. Moonflower dragonsblood is my favorite.

Fruity Fun
I purchased the watermelon sugar, pink lemonade and the pineapple one. Love them all my kids fav is the watermelon sugar. I have horrible allergies and sences really trigger them and so far anything I have bought from birds of Valhalla have not triggered my allergies. My favorites are alway the fruity ones. Just my preference. Will buy again before they leave for the summer.
