I always had a
personal rainbow in my mind, where blues, cold greens and purples took the major place of it, but tertiary and quaternary (and so on :D) colours are something really fascinating to me.
What's these introduction got to do with nailpolish?
I don't know :D, but I like duo-tri-multichrome varnish not only for the colours you clearly see with a glance, but for the colours "at the edges" too, which are often a sum of the firsts, even if it can be hard to spy them once you apply polish (and if you have flat nails).
This is my last multichrome haul:

Stargazers are n. 307 (left) and n. 161 (right): "Space Cadet" dupe the first one, awesomeness in a ball bottle the second one.
N. 161 is a
blurple-
prussian blue JELLY base filled with golden-green shimmer, Nihrida
swatched this, but at that time my bottle was already on journey toward my Helmer, so I chose it on eBay just by instinct :D

And the best part is the price: I paid like a total of €5 for two bottles, shipping included; bottles are of 14ml, made in UK... Gorgeous.
But few days ago I visited a Layla stand and found these two too:

Not blues! :D
But I literally fell in love with them *_*
Metal Sense is one of the million ranges Layla has just for its nailpolish division, lol.
I didn't even know about it before seeing these bottles last friday, everytime I discover a new one.
As usual, swatches/images on site are ridicously off from the
real appearance, but I am (we are) here specifically to help buyers out there :P
N. 11 is a metallic version of "Space Cadet", while n. 9... I don't know, I don' t have a similar colour.
Violet-to-pink-to-a rusty bronze *_*
Here I show you how they change on the bottle cap,
one coat over a coat of black:

I like them because they're
truly metallic, I mean, with that grainy texture, like infused with a fine metal dust.
But... there are two flaws.
First one - not for me, but I know some girls (or boys?) keep this in consideration: they're not B3F.
I highlighted ingredients list on one bottle, and you can read "formaldehyde resin" and "toluene"; according to
this post by AllLacqueredUp, formaldehyde resin isn't toxic.
I don't know if other components are bad as well, but I guessed they weren't safe just by the smell, then I checked ingredients :D

Well, maybe Layla too will become aware of this and completely stop making polishes using toxic substances; I have two of their Ceramic Effect and they're safe, no bad stuff.
Second flaw, price: they're like €7 each, but you know my mind, original (or well made) products are worthy a little higher expense. And they're made in Italy too :>
What do you think?
Have a nice day/night/whatever and thanks for your attention
