I got a 1ml sample size as 5ml was out of stock and I couldn't afford Rose Otto. I wish I could compare these two but can't. This Rose Absolute has nice scent but not quite what I expected, and I have to say I've smelled nicer scent of Rose Absolute before. Nonetheless, this is lovely and if you want to add Rose Essential Oil, this is worth trying. If you only need a drop or two at a time and won't be needing it frequently, 1ml is surprisingly enough. 1ml tiny bottle has a little cap and it was stained bright orange colour, which was a bit of a surprise.
