I love the thick tip because it saves time! It's all you need to achieve a smudged finish, even at the beginning of your brows. As expected from Fasio, it lasts longer than other brands. My brows are soft and sparse, and I often want to fill in areas, so a thin tip takes a lot of time. I also like to fill in the beginning of my brows quite a bit. I think the trick is to apply the brush quickly, without applying too much pressure, and to glide it evenly across the entire area. The thin tip is not sticky, so the stiff tip makes it easy to shape the end of your brows, resulting in beautiful brows without being too thick. Drawing the end of your brows at the edge, like a calligraphy stroke, creates a sharp, gradated look. For the beginning of your brows, I found it helpful to hold the pen upright and fill in softly with small strokes. It's not easy to create the perfect brow shape from your natural brows, but this brush is incredibly useful because it consistently creates a natural, beautiful look without the need for powders, brushes, or other tools. It does require some technique, but once you get used to it, it's a breeze because you don't have to draw in tiny details. Since you can fill in the entire area, it's easy to create the perfect shape. It may not be suitable for those who want a sharper look or if their eyebrow hair is hard or dense. There aren't many manufacturers that offer thick cores, so I hope they don't disappear. It may not be suitable for everyone as it depends on the hair type and the way it grows, such as how easy it is to draw the end of the brow, so it may not be for everyone, but I would like you to try it once. Suitable for: Those who want to save time, those who want to draw many areas overall, those who prefer a slightly softer look rather than a sharp one, those who like natural brows, those who tend to draw too many brows. Suitable for: Those who want to take their time to carefully create their brows in detail, those with hard hair, those who want the end of their brows to be very thin and sharp, those who wear heavy eye makeup and want to make their brows thicker, those who want to draw in a specific area.
