The pen and stamp are two different shades.
I tried the brown one the other day. I started by using the pen and lining my eye and then used the stamp and noticed they were 2 different shades, so it did not look good when I tried to connect it. The picture is an example on my hand of the difference in shades. I have the black liners and have not had a problem but the brown was disappointing.
