Best pen eyeliner I’ve ever used, I won’t bother with other brands any more. The tip is a tiny, ultra-fine BRUSH, not a felt tip . . . so if you drop it, the brush hairs just go right back to being as pointy as they were before. The product flows very well into the brush tip and as long as you cap it after use, it will last MONTHS, where most pen liners I’ve had only last a few weeks before they dry up. It is the blackest black you can imagine, and you can get anything from a super fine line to a thick bold one very easily. I haven’t noticed any difference in my eyelashes, but it’s still more than worth the money just because it’s such a fantastic liner.
