It is something you need to get your sticky mitts on to be sure-er isn't it?
I went to TKMaxx at the weekend, to have a look at what's coming out of the far east. I was very surprised by how good some of it was, and at the newer features being used - lots of Batutto cut, lots of things with what is either crude glitter or
maybe even be mica in them (I didn't have my close-up, peering glasses with me).
Some of it was really well executed and delicate, BUT the big giveaway was at the end of a few minutes handling it, my hands felt that horrible gritty greasy way and they absolutely stank of acetic acid. Not a nice vinegary smell, but a BDH Winchester of pure chemical smell. eeeee-yeuwk!

Maybe leave this bottle alone for a while - don't wash it, see if it gets greasy and smelly. That would rule out or in a Chinese attribution.
