Most of what you pay for in a small bottle of oil is the bottle.
Bring yours back, washed and dry, and we refill it by weight. A twelve millilitre refill of most of our attars is between a third and a half less than a new bottle, and there is no difference at all in what goes into it.
We do this for anything we sell in oil form. We also refill bottles bought elsewhere, provided you can tell us what was in it, because oil poured into a bottle that held something strong takes on whatever is left behind.
The only thing we will not do is refill an old bottle with a famous name on it. Not because of the oil, but because a bottle carrying somebody else's label and our oil is a lie waiting to be told to the next person who picks it up.
