What to know before buying
- The stated 24-hour wear and water and smudge resistance are manufacturer claims, not independently verified performance. Customer feedback is mixed on lasting power and smudging, and some customers report the pen dries out. The listing also varies between medium and full coverage descriptions, so the coverage level is not consistent.
Who is it for?
A good fit for
- Buyers looking for a black liquid liner with a flexible brush tip for varied line thickness.
- Those who prefer a matte finish and a vegan, cruelty-free formula as listed.
Less suited to
- Buyers who need consistent assurance about how long the liner will last or whether the pen will remain usable, given the mixed feedback on wear and drying.

Customer feedback highlights smooth application and ease of use, but opinions differ on longevity, smudge resistance, effectiveness and value. Some say it stays on all day, while others report smudging or that the pen runs out after one use. Drying out is also a reported concern. These experiences matter for a liquid brush-tip liner whose listing claims long wear and water resistance, but the feedback does not establish how any individual pen will perform.

Mixed feedback
