I chose "86" which is a dark green and close to my hair colour. I bought it off ebay, for under $20 including shipping. This brand is available in Australia via their website, but I'm a bargain hunter so I got it cheaper on ebay.
It comes in a small jar, and I use a small makeup brush to do my eyebrows. The gel is very smooth and creamy to begin, but it dries quickly when on the skin. I tried a bit on my hand, and it was very smudge proof. I kept rubbing it, but it wouldn't come off!
For this colour, I found a needed to layer it a bit because it was sheer if I didn't pick up enough product. I didn't want to have super green eyebrows, so I felt this was a positive thing because it kept my eyebrows more 'natural'.
