Awesome brow liner and gel
Color: 259 ASH BROWN, Size: 1 Count (Pack of 1)
Love this pen! Just wish there was a color inbetween the medium brown and the ash brown. I love the brow gel in it though! The pen is nice and makes hairlike strokes that make for a more naturally filled in brow. The gel holds in place all day!

Benissimo!
Color: 250 BLONDE, Size: 1 Count (Pack of 1)
Hands down the best brow pen I’ve used & I have used ALL of them! I love this for my almost non-existent brows. It’s easy to handle for precise hairlike application. Have subscribed to this it’s so good. Finally, one that’s the right color, doesn’t run out even after a month of use & is the BEST price. Maybelline for the win!

The colors are way off
Color: 259 ASH BROWN, Size: 1 Count (Pack of 1)
The ash brown is basically black. However, I do think the gel helps set the brow color and I have been using a ash blonde color and then applying the gel.

So Good!
Color: 262 BLACK BROWN, Size: 1 Count (Pack of 1)
This is my absolute favorite bow pen I've ever tried. The brush tip is incredibly fine and makes each stroke a perfect hair like finish. I tend to get heavy handed with other options like brow powders so having an option for thin hair like stokes makes it incredibly hard to taken it too far. The tip doesn't dry out to the point of skipping or Inconsistency without you knowing its time to refresh it by capping and shaking, but I do find that it comes back refreshed and even better the more you repeat the capping and shaking step between brows. Easy to hold and design. I wasn't totally blown away with the brow gel it comes with attached to the pen when it comes to hold power. It doesn't flake at all and doesn't leave a cast of white or sheen to the brow, which is a plus. It's just a nice way to loosely set the brow after application. There is some wiggle room with wiping the product off with a q tip if a mistake is made, but once the pigment is dry, it doesn't budge all day, even after intense exercise or humid conditions. I'll be repurchased this like... now, and hope it never gets discontinued!

Defective product from Amazon.
Color: 255 SOFT BROWN, Size: 1 Count (Pack of 1)
I have used this product many times and I think it is a good product. I usually buy it at Target. The product I received from Amazon was defective. The pen was totally dried out and I was not able to paint a brow. There was liquid in the brush side, but it is colorless and meant to be a finish to make the color last longer. Maybe just a one time fluke, but I'd purchase this elsewhere.
