I purchased the storm, au natural and oh so special palettes off the sleek website and it was all quite cheap (around $18NZD each). I bought these as an alternative to the highly popular naked palettes.
All i can say is wow! For the price, these eyeshadows are amazing. There is a combination of mattes and shimmers to choose from. I found all of the colours were quite pigmented and easily blendable. However the whites in the palettes were not as pigmented. I tried using an eye primer underneath the eyeshadows and oh boy, the colours turned out so much more intense and lasted longer.
Overall the quality of these eyeshadows are really good and i would highly recommend buying them for a cheaper option compared to more high end brands such as urban decay.
I wanted to love this sleek palette (I have Oh so special) but I just found myself never really reaching for it.
There are some awesome colours like Noir (matte) Celebrate (shimmer) and gift basket (shimmer) but in general I found the colours just didn't really suit me, especially the quite pink toned ones. I am pale with blonde hair so that could have something to do with it. I also found some of the colours a bit chalky and the shimmers actually applied stronger if you used your finger instead of a brush.
In terms of the packaging it is pretty 'sleek' but is made of similar material to NARS products so it gets dirty pretty quick. Also the clasp to close the palette could be a bit tricky to open and close which I found really annoying. I wish this palette came with a brush instead of those horrible foam applicators.
Overall I think this is a good palette if you are looking for something more affordable with a range of colours, mattes and shimmers. But if you are pale it may pay to go with one of the other Sleek palettes with a more suitable colour range. I will be looking to try a different one sometime soon!
Tips: Use a primer to intensify the shadow colours and make them stay on longer.
