I live in the UK and only just discovered Sleek in the latter part of last year. Our Superdrug only started to stock it recently, too, and we live in quite a big town.
I love the palettes, and the eye dusts (I bought one of the packs of 10 in the 50% off online sale, so bargain!). The blushes are great, too. However, the glitter eyeliner wasted no time in migrating glitter all over my face, so I won't be buying any more of that. The Pout Polish comes in beautiful colours, which glide on smoothly and feel great on the lips, giving a hint of colour, too. They smell amazing in the pot, but I found after a while I got a bad taste in my mouth - not from licking my lips or anything, but simply by inhaling the 'fumes' from it through my mouth. I tried both colours I have, and they both do this to me, but none of my other lip balms/glosses do. Shame, because I really loved them otherwise.
