I promptly presented myself at the Pixi store on Carnaby Street to see what all the fuss was about. The extremely helpful sales assistant explained that the eyeliners were Pixi's best-selling products and assured me that once applied they wouldn't budge. I sniffily decided to test this claim and drew a line of Black Silk on my hand, waited a moment then tried to smear it. It actually didn't budge! I was sold and snapped it up immediately before hot-footing it home to try it out for real.
Clearly my application technique is woefully mediocre so I shan't try and tell you how to do it. However, if you want to watch some excellent tutorials on all things make-up related you absolutely must check out another 'pixi' - Pixiwoo on YouTube, if you haven't already. They were my first port of call in perfecting my eyeliner technique years ago (as perfect as I'm capable of, anyways). I used this tutorial here.
Back to the eyeliner pen: as you can see it features a long tapered nib that makes it possible to get right into the inner corners of the eye. Black Silk is a true black and when it's on it really does stay on all day, with the added boost of being waterproof. My main problem with the majority of eyeliners I've tried over the years is their tendency to transfer to my upper eyelid, I've never found one that doesn't. However, the transfer from this product really is minimal, I can't say enough how impressed I am with it and it has completely usurped gel eyeliner in my make-up bag. It costs £12 per pen, which I think is very reasonable and I shall definitely be buying it again. Go, Pixi, go!
