I recommend the Tahiti Freesia Rose Diffuser.

This is the Tahiti Freesia Rose Diffuser that I have been using several times because of its lovely scent.

The capacity is 200ml, and you can purchase it for about 10,000 won per 100ml.

It's cheap for this amount, and it's refillable.

You can use it in your car or in your room.

I think I see this diffuser being used a lot when I visit bookstores or regular stores.
