I've already shown two other polishes from this same limited edition, both also for "Lacke in Farbe ...und bunt!". I have to say that I really enjoyed the collection overall, looking back; at the time, I wasn't all that thrilled. In any case, this seemed like a nice fit for purple.
You may or may not be able to make it out in the photo, but this polish has a slightly jelly-like formula. It should work out fine for you in two or three coats. Of course I added top coat as well - gotta get that shine on, peeps!
