Worry-free shopping
This was exactly what I was looking for! What a lucky find! I added some essential oil and carrier oil and a tad of food coloring for effect... It's hanging in my car and now all my friends want one! I’ll keep buying more! ❤️
I find it a bit difficult to put the oils in, so I guess for me it would’ve been better if they came with fragrance already… otherwise it’s great, good quality, reusable
I like that they have an adjustable strap and a secure lid. No spills, not in the way when driving, and the total freedom in choosing the scent. Love it!
Everything came as described, good material. Easy to fill with fragrances and they came with rubber pieces to ensure no leaking until used
The design is cute, but I wish the bottle was a bit bigger.
They are good size and so cute. They came very well packaged. I can’t wait to use them. Definitely value for money.
These are very nice bottles and are bigger than most & they do not leak! A bit of advice: Make your car diffusers with real essential oils - do not use fake fragrances that are harmful. A few drops of a true unadulterated essential oil is plenty and you'll feel the difference. Do a little research, you'll be glad you did.
Love these way more than regular air fresheners for cars!! I can add the scent that I like, change scents, or just use them for decoration. And they’re reusable, which is also great!! You need to not screw the lid on too tightly after placing the oil though.
You can put whatever scent you want in these. I use one in my car.
