FYI please note the slight change to the name of this product. For years now when people order 10ml at 1%, I've usually sent them about 1ml+ at 10% as that's how the material arrives from the manufacturer (and people tend to prefer things more concentrated where possible). I'm just going through my products at the moment and formalising things a little bit so I've now updated it to be more consistent :)
