It's thin and easy to draw.
This one is in Thunder. I'm a wandering eyebrow artist. My hair is often blue, light blue, or silver, so I've been searching for a thin eyebrow liner. Cezanne's ultra-thin eyebrow liner is hard and breaks easily, making it difficult to draw. I tried various eyebrow liners, but they were too dark and I couldn't stand the idea of eyebrows darker than my hair. "MAC has a wide selection of colors, and the store clerks know a lot of people who enjoy hair color, so they must know..." I thought, heading to a store. They recommended this Thunder liner. The clerk I happened to talk to also mentioned that she used to have light blue hair, and she taught me how to draw eyebrows that way. In my case, my eyebrows are quite dark, so I bleach them, draw them here, and then apply a light MAC eyeshadow powder (Omega) to draw them. I sometimes use blue eyeshadow as well. That's the only way I can create eyebrows that match my hair color. This is probably a bit unusual, but if you have very light, cool-toned hair, I'd love for you to try it! It's soft and easy to apply. However, as everyone else has said, it wears out incredibly quickly. It's gone in about a week. It's just not worth the money. What's going on??? 3,600 yen for a week's worth of eyebrow pencil is a bit much. And while the advantage is that it's thin and smooth, it also has a weakness: it sometimes snaps and breaks easily. I've probably broken hundreds of yen's worth of pencils... but this sander is out of stock everywhere. Is it going to be discontinued? If it is discontinued, I'll have no choice but to rely on Cezanne powder for my eyebrows... Either it gets discontinued first, or I go broke because I don't own an eyebrow pencil. ^_^ Japanese manufacturers don't have a light gray eyebrow pencil, for now. The only thing I could live with was Cezanne's gray eyebrow powder. Other than that, there really aren't any other grays. Most eyebrow pencils are brown, too. Sometimes there is grey, but it is either a dark grey for people with black hair, or it is usually yellowish, and only the eyebrows are brown. I just can't stand it!!
I think these eyebrow pencils are super easy to use! I have quite large brows, so I've been using thick eyebrow pencils to quickly draw them in, or I've been using powder and then correcting them with a pencil, but thick pencils and powders make it hard to draw the ends of my brows, so I bought this one. I've tried a cheap, thin one before, but it broke easily and was hard to apply, so I didn't buy it again. This one has the perfect hardness, and I found it less likely to break! The screw brush is on the other side, and the cap is translucent, so you don't have to worry about which one is which, which is great! The only drawback is that it draws so smoothly that it seems like it will run out quickly, so it doesn't seem like it's very cost-effective... but it has significantly reduced the stress of drawing my brows, so I would definitely recommend giving it a try!
