a while ago i was looking for a matte topcoat and i found an offer on Rimmel polishes: "get one Rimmel Pro nail polish and you get a matt topcoat for free!"
Since i never had any kind of Rimmel lacquer i chose the first color that crossed my eyes without paying much attention to it (my main interest was the matt topcoat).
When i tryed it i was so amaized by it's shine, i don't know if it's the color effect or if it's the product itself, also the texture is reaaaaally smooth and another particular thing is the flat/wide brush that helps getting a good application.
The polish is a very very dark eggplant/aubergin brownish color, n° 416 night flight
(didn't find it among the list on their website though)
unfortunately there isn't a wide range of colors! -only 16 shades-
i also wouldn't say "mistake free application", the wide brush does help getting a more precise application, but perfection is achieved through practice anyway ;-)
