Cheap and effective
I use this to tint my eyebrows.  I love it so much because it is so cheap and literally takes about two minutes to use.  I use a damp q-tip to wipe it off when done. The tint lasts a few weeks for me before it completely fades.  At first, it is a little too dark/fake looking but I use brow makeup over it anyway when I go out to achieve a more perfect look.  A year later, I am still using the same package I purchased last year.  I have sensitive skin and have had no issues.  Be careful though, it stains counters, ...everything..if you make a mess.
