Surprisingly the paper did not soaked by it, but it was kinda tricky. I used toothpicks instead of the nailpolish brushhead. I would only recommend it if you have enough free time for experimenting with it. Or I would suggest to use those sparkling, transparent colors, which can be added on pencil/pen/etc. colored areas. I only tried it because I didn't found my color pencils ^^' The colors by nailpolish looks great, but I think they won't last for long.
