Asked Questions

Can I use 999Scala scent oils with any diffuser?

Can scent oils be returned if I do not like the fragrance?
Scent oils cannot be returned or refunded once opened, used, seal-broken or tampered with. Fragrance preference is subjective, so personal liking, sensitivity or change of mind is not considered a valid reason for return or refund.
How should I store scent oils?
Store scent oils in a cool, dry place away from direct sunlight, heat, open flames, children and pets. Keep the bottle tightly closed when not in use.
Are 999Scala scent oils safe to apply on skin?
No. 999Scala scent oils are intended for compatible diffuser use only. Do not ingest them or apply them directly to skin.
How long does one bottle last?
Usage depends on diffuser model, intensity setting, schedule, room size and frequency of use. Lower intensity and scheduled diffusion will usually make the oil last longer than continuous high-intensity use.
