Each of these pens cost about 4 € and have a thin metal tip and a striper brush. As these are Hallowe'en items they come in four 'typical' colours:
- black - basic black creme
- green - shimmery, my favourite
- orange - bright creme
- yellow - almost neon
The first swatch-photo is badly lit, but gives you a pretty good idea of the colours on white, while the one I took with flash is pretty awesome for showing the colours on the black base.
Spooky Nail Art Pens are pretty good quality, easy to use, and the striper brush is very skinny. If you want them to dry you absolutely need to use top coat!
I got these at BIPA, maybe they are cheaper now that Hallowe'en is over.
