frequently asked
what does onyx smell like?
clean, bright and island-inspired — the feeling of warm air and long days rather than any one dominant note. it's the most easy-going scent in the range, which makes it a safe choice if you're buying as a gift.
how big is the extra large, and how long does it last?
2200ml. the bottle is 280mm tall and 115mm square, with 600mm reeds — a floor or console piece rather than a shelf one. as a guide, around nine to twelve months.
is onyx a good choice if i don't usually like scented things?
probably yes. it's fresh and light rather than sweet or smoky, and using only half the reeds keeps it very subtle.
how do i set the reeds up?
put all the reeds in, leave them an hour or two to draw the oil up, then turn them over once. after that, flip them every week or two to refresh the scent — that's all it needs.
wash your hands after handling the reeds, and don't put used reeds back in the bottle.
can i make it stronger, or make it last longer?
yes — it's controlled by the reeds. more reeds means a stronger scent that gets through the oil faster; fewer reeds means something subtler that lasts longer. start with about half and add more if you want more.
where's the best place to put it?
somewhere with a little air movement — a hallway, a landing, near a doorway — rather than a still corner. keep it out of direct sunlight and away from radiators, which will burn through the oil quickly.
stand it on a coaster or tray. fragrance oil can mark wood, painted surfaces and polished stone if it drips or is knocked.
is it safe around children and pets?
keep it out of reach of children and animals, and don't put it somewhere it can be knocked over. the oil is an irritant if it's swallowed, or if it gets on skin or in eyes.
can i return it if i don't like the scent?
only if it's still sealed. once a diffuser has been opened we can't take it back for hygiene and safety reasons, unless it's faulty. unopened, you have 14 days from delivery — see make a return.
how quickly will it arrive?
orders are packed and dispatched within 2–3 working days. uk delivery is free on orders of £40 or more and £3.95 under, or choose express at checkout for £5.95. extra large diffusers always go free.
