There are 10 pens in the set and each has both a brush and a pen end to it. Unlike a lot of other nail art pens I've come across, the brush isn't a striper, but a full brush - which means you can paint the whole nail with the polish first.
The pen end and the brush end
A couple of swatches of all 10 colours in the set:
For nail art pens (rather than what I would call 'proper polish') the polish is of a decent quality (though the yellow is, as most yellows are, a bit streaky to work with) - all the swatches above show two coats, which was certainly sufficient. They painted on smoothly and dried pretty quickly. I have to say, though, that I find the pen ends quite tricky to work with - usually I would use a striper brush for my nail art - so the more intricate designs were a bit of a challenge! The polish had a tendency to blob out of the end (funnily enough most frequently with the reds), and some colours came out more vividly than others - the lighter ones didn't work so well on darker colours. Overall, though, I thought they were fun and make a great addition to my collection - and I'm sure would be a fab gift for any budding nail art enthusiasts.
