Reputation for long-wear/no-smudge performance
Many buyers purchased specifically because they had oily or hooded eyelids and heard this liner survives sweat, oil, and rubbing better than competitors like Kiss Me Heroine Make or Stila.
Influencer/YouTuber and word-of-mouth recommendation
Several reviewers say they bought it after seeing it recommended by beauty YouTubers, 'Director Pi,' or because it was widely discussed online ('話題なので').
Repurchase/brand loyalty
A large share of reviews are repeat purchases, with customers stocking up on multiple colors or rebuying the same shade after finishing a bottle.
Affordable alternative to prestige brands
Reviewers compare it favorably to $25 Sephora liners or luxury brands like Stila, citing similar quality at a fraction of the price.
Fine brush tip for precise application
Buyers, including beginners, cite the thin, controllable brush tip as a reason to choose this over pen or felt-tip liners for thin lines and winged looks.
