These are a combination of Barry M, Miss Sporty and Hot Looks nail varnish, generally the cheapest of the bunch. 'Hot Look's is actually the cheapest of the lot in most stores, but I find that it only requires one coat, the colours are vivid, it dries really quick and doesn't chip that badly. So weirdly I like using them, it's just matt colour but you can get variations.
In case you are interested, what I can work out from the images is in the TV show, the nails go (starting from thumb) red, yellow, purple, orange, and green/teal/blueish. But the thumb could be magenta while the orange is red, but I've done it the way it looks on the barbie hand. (Also excuse the writing on my hand, university room notes and other stuff, lol.)
So yeah, hope you like!
