I only own one of these - in rich red. I got this directly from the ELF website and it was US $1.50 (I got it during a 50% off sale, so RRP is US $3.00 on there).
The shade I got is 'rich red' - which, as the name suggests, is a rich, vibrant blood red.
Unlike other lipsticks, the packaging for this is long and thin. You twist the end of the lipstick up to disperse the product and apply it like any other lipstick.
The formula is slightly dry and a little stiff but definitely useable and not difficult to work with. The pigmentation is insanely high and very true matte.
Because it is a matte lipstick, you probably want to prime your lips before applying this - or apply a lip balm. I haven't found this supremely drying but I do like to prime my lips before wearing this as they are quite dry naturally.
A hidden feature of these is that you can pull the bottom off them and inside is a sharpener for them! I think this is really awesome and makes it super easy if you stash this in your handbag or take it when traveling.
Overall I think that for the price these are a steal and I am definitely heading over to iherb to purchase more.
A workmate of mine gave me a lot of e.l.f lip products, and the matte lip colour in praline being my favourite. What i love about this product is that it is long lasting and has a beautiful matte finish. I found myself only touching up once or twice at work where i talk to customers the whole time and eat and drink regurlarly which is amazing because other products i have to re apply a lot. I personally adore dark colours so i would apply two layers but if you want that browny-nudey look, than its perfect! What i didnt like was that i went through the product in very short months and also you must moisturise and for very dry lips to use a lip scrub before because with most matte products, after a few hours it can dry out. But this product is creamy and never gives a cakey look. over all i love it and its a must-have.
Tips: Exfoliate and moisturise before use
