For reference I am MAC's NC40 - since different skintones can affect the look of a nail polish :)
I am not sure how to really describe this pretty nail polish. It has a satin finish, like hot pink almost. I'm not sure why they have blue in the name since the colour to me appears to be just rosey dark pink.
The lasting power is good if you use a top coat. The formula is not too thick or too thin and I've had this for a long time - maybe 3 years and it's in really great consistancy still.
The brush handle is pretty long so you can have a good grip and the brush itself is thin (perfect for small toe nails) and I would say the bristles are abotu an inch long, maybe a tad smaller.
I would buy this again but I'm always the one to try new things :)
