Scent: Peony Princess

Top up the diffuser you already own. A 150ml glass bottle of our fragrance oil, blended from high-quality fragrance components on a clean, low-odour base so the scent comes through exactly as it should — nothing muddied, nothing synthetic-smelling underneath.

  • 150ml glass bottle: enough to refill a standard 100ml diffuser and top it up again
  • Clean base: low-odour and slow-evaporating, so the fragrance lasts rather than flashing off
  • Child-resistant cap: every bottle ships with a safety lid
  • Works with any reeds: pair with our fibre reeds, or the ones already in your bottle

How To Refill

Getting the most from a bottle

A refill takes a minute. These are the things that decide whether it smells as good in week six as it does on day one.

Let it run dry

Wait until your diffuser is nearly empty. Topping up a half-full bottle muddies the two blends and dulls both.

Fill, don't drown

Pour in roughly two thirds of the bottle. Reeds draw oil up by capillary action, and a bottle filled to the neck simply spills when the reeds go in.

Fresh reeds, every refill

Old reeds clog with evaporated oil and stop drawing. New ones are what bring a refill back to full strength.

Why the base matters as much as the fragrance

A diffuser oil is mostly carrier, not fragrance. A cheap carrier evaporates fast and carries a solvent note of its own, which is why some refills smell sharp for a day and then of very little. Ours is a clean, low-odour base chosen to evaporate slowly and stay out of the way, so what you smell is the fragrance you chose.

  • Flip weekly: Turn the reeds over once a week to refresh the throw
  • Expect 6–8 weeks: From a full bottle in an average-sized room, with the door kept shut
  • Use more reeds for more scent: Add reeds to strengthen it, remove a few to soften it
Fill to about two thirds Reeds displace oil — leave room at the neck ⅔

Frequently asked questions

Will it fit my diffuser?

Yes — it works in any reed diffuser bottle, ours or anyone else's. A 150ml bottle fills a standard 100ml diffuser with enough left over to top it up later.

Can I use it in an electric or ultrasonic diffuser?

No. This is a reed diffuser oil and is not water-soluble, so it will clog an ultrasonic diffuser and may damage it. Reeds and a bottle only.

How long does a bottle last?

Six to eight weeks from a full diffuser in an average-sized room. A warm, draughty or open-plan room gets through it faster, and more reeds means more scent but a shorter life.

Do I need new reeds every time?

We would recommend it. Reeds clog with evaporated oil over time and gradually stop drawing, which is usually why a refill seems weaker than the original. Fresh reeds bring it back to full strength.

Can I mix two scents?

Better not to. Pouring a new scent onto the remains of an old one muddies both. Let the bottle run almost dry first, and start the new scent with new reeds.

Why can I not smell it any more?

Usually one of two things. Noses adapt to a constant smell within a few days — visitors will still notice it. Or the reeds have clogged, in which case flip them, or add a couple more.

What is actually in it?

High-quality fragrance oil on a clean, low-odour carrier chosen to evaporate slowly. No water, no alcohol burn-off, and nothing that smells of solvent underneath the fragrance.

Safety advice

Fragrance oil is concentrated. Please read this before you open the bottle.

Do Not

  • Let the oil touch polished, painted or plastic surfaces — it can mark them permanently. Stand your diffuser on a coaster or tray.
  • Place near an open flame, a heat source or anything that could ignite it.
  • Allow contact with skin or eyes, and never swallow the contents.

Safe Practices

  • Keep the bottle out of reach of children and pets, and replace the safety cap after pouring.
  • Refill over a sink or tray, and wash your hands afterwards.
  • Store upright somewhere cool and dark, away from direct sunlight.

If oil is spilled or swallowed

Wipe spills immediately with a dry cloth, then wash the area. If swallowed, do not induce vomiting — seek medical advice and take the bottle with you.
