I bought ETUDE HOUSE Petit Darling Nails Matte nail polish in "Java Blue", which is a matte black shade, from a Korean ebay seller recently. Though the shade is very pretty, I'm not a fan of the brush or the polish formula. The bristles of the applicator brush are not straight and leave streaks, and the polish stays matte only first few hours! It also seems to sorta crack, and make nail ridges very prominent, as you can see in the pictures. $5 down the drain! Definitely will not recommend!
Etude house "Java Blue" on ring finger, Street wear shine divine in "Black Divine" on the rest.
Well needless to say I didnt leave it like that for long, and changed the ring finger nail paint into something different. I used a sponge to apply blue and violet polish over the Etude house polish and following that I applied a glitter polish over it (Inspired by AndreasChoice outer space nails video).
