Aritaum Idol Brush Liner

This is the Aritaum Idol Brush Liner. I purchased shade 2 Brown, but it is actually closer to black. The brush is thin, making it easy to draw tails or under-eye lines. It hardly smudges, so I am using it well. Brush pens often dry out quickly or don't write well, but this product writes so clearly that it has never come out faint.
