The colors are easy to apply (preferably a cotton swab or other thin pen take it) and dry quickly (approx. 10 minutes), if that is too slow, simply blow shortly. The luminosity and the neon effect in the dark are really good, under blacklight absolute wow factor. We have used the color with 8 people on 2 evenings and had more than enough of it. Compared with the other colors on Amazon therefore a good price and very good lighting effect.
I had already bought other colors on Amazon, so far this performance were here under price / definitely the best.
