When I first started getting into make up (10 years ago) i used to have quite a collection of these pigments. I had all different shades but clearly remember falling in love with the Cornflower Blue, it was my absolute favourite. I used to use these with no primer (back in the days before primer was a thing) and these still lasted all day. Very very pigmented, you don't need to use much to get a stunning eyeshadow look.
I haven't repurchased them since as it was relatively challenging to purchase (before the new stores existed and I brought onine and got it shipped to NZ) and I find it too pricey. It is a great quality product but I believe I could get similar results for the fraction of the cost.
I can not rave on about these pigments enough! They are amazing! Sooo pigmented and you get so much product. You only need the tiniest bit and the staying power they have on the lid is out of this world. Would definitely reccomend applying a base coat before hand for best color pay off. These pigments do not fall out and when i say a little goes a long way, i meant it. I tap the tip of my fluffy brush and pat gently onto the center and inner corner of my eye. The packaging is easy to use and comes with a screw top lid. Affordable pricing. Highly reccomend.
