Tip will not stay saturated with color
Color: Honey Brown, Size: 1 Count (Pack of 1)
This is a pen with a nice felt tip. First time I used it, it glided on nicely. Second time used about it a week later, tip was dry and no matter how I tried, it would not saturate and provided no color. I even tried storing it with the tip facing down to make the color flood to the tip, but even after several days of standing it up that way, tip was still dry. What a waste of money. I just ordered their Easy Brow and Fill Tool, which is a stick of color that winds in and out and so far like it very much. Would recommend that and not this ink pen.

Always Perfect!
Color: Rich Brown, Size: 1 Count (Pack of 1)
The best brow liner I have ever used. My eyebrows have thinned over the years because of a thyroid condition and I have been drawing them on since I had was in my thirties. I believe it really retains my youth and the fact that this is a liquid helps me keep the hairs in place that I already have up there. I do not go anywhere without my eyebrow liner. Add this to your makeup kit! You will thank me.
