The Anastasia brow products are very well-known, so I purchased the product. However, the Brow Wiz product, which has a thinner core, has similar products from other brands, so I purchased the Definer product, which has a thicker triangular core. The color is Taupe, a light brownish shade without any reddish tones, which is a good base color. It doesn't apply too heavily but goes on smoothly, making it a product I reach for frequently. While it can be wiped off with friction on the applied area, I didn't notice significant smudging or fading in my daily life. The built-in brush is also of good quality, and the core hasn't broken even after using it for several months.

The downside is that the cap can become a bit loose over time, but it doesn't easily come off. Overall, I'm satisfied with using this as a daily brow product.
