PaddywaxPetite Collection Scented Oil Reed Diffuser, 1.5-Ounce, Sky Blue-Wild Fig

Are refills available or do you have to purchase the whole kit again?

Which scent is the strongest?

Is there a refill available for the wild fig scent?

Would this size be too strong for a cubicle in an office? The person closest to me is probably about 6 ft away and separated by a cubicle wall.
