I have before purchased another shade which is also matte (review here) from Sleek's True Colour lipstick line and do indeed love it but I think I just love this shade way too much more.
Comes in short oval black casing like all of their lipsticks, has a slight rubbery feel so will probably attract fingerprints quite easily.
Sleek True Colour Lipsticks have two finishes of lipsticks in their range which are Matte and Sheen and contain Vitamin E without any scent or taste.
Mystic (Matte) - A strong bright and powerful purple magenta which is a true matte and opaque.
The formula can be drying as with most matte lipsticks but it's quite light on the lips considering.
I find that this lipstick lasts for hours on me unless I have a meal then it will start to wear off but you're still left with a even layer of pretty magenta stain. Generally I think most matte lipsticks will always last longer.
