When I was younger a lot of my friends were using sleek, and I never thought it was any good. However they defiantly have quite a few gems on their stand, one of them being their palettes.
Highly pigmented, long lasting, inexpensive and with a decent selection, at £4.99 for all this great qualities I think they are a great buy! The palettes include both matt and shimmery shadows, and all include one matt black.
The original palettes is the first one I bought (sorry I have no swatches) it is very pretty all colours are shimmery, and the range of colours is great.
This one is the Sunset palette, which I really like, although it can be hard to wear reds and pinks without looking tired, the different tone means there is defiantly one for you, and there is even a blue perfect for lining the water line.
This is my favourite, the Storm palette; this is a great palette for people like me who wear boring old neutral colours every day. The blues and greens are even dark enough to not draw very much attention and are still quite neutral.
The acid palette has amazing, bright, neon colours as well as some more wearable ones. It has a perfect balance between matt and shimmery colours, great palette if you are a little more daring with your eye makeup
