I bought this highlight brush from Shinobu Igari! It allows you to apply highlights to even the smallest areas with a single stroke! It's a time-saving item! ☆Brush Shape: The handle is long, and the brush is thin and flat, not rounded. It has a firm texture, and at first glance, it looks like a paint brush! ☆Usage: I use it for pressing powder highlights. It applies highlights to the desired area with a single stroke! It's much faster and easier than applying highlights with the included brush or tip! It seems like it could be used for shading or highlighting with a different texture. ☆How to Use: I bought it after seeing hair and makeup artist Shinobu Igari use it in a makeup video. It's useful when you want to apply highlights in Igari's unique way, that is, when you want to apply highlights in various small areas (I apply highlights above the brows, between the brows, around the inner corners of the eyes, and in the triangle zone). The included tips and mini brushes are too small, and brushes designed for the C zone are too large, making it difficult to target small areas... This product solves that problem! You can do your makeup without it, but having it will dramatically improve the quality and speed of your makeup application. On the other hand, if you only use highlighter on the C zone, the brush may be too small and difficult to use.
