Low price / value for money
Reviewers repeatedly call it 'cheap but good,' 'unbeatable for the price,' and buy it explicitly because it delivers quality comparable to pricier brow pencils like Benefit or Innisfree.
Repurchase loyalty
Numerous reviewers mention repurchasing 2-10+ times over multiple years, indicating strong repeat-buy behavior once tried.
Word of mouth / SNS and staff recommendations
Some Japanese and Korean reviewers say they bought it because it was 'famous on SNS' or recommended by Olive Young store staff.
Gift purchases
Several reviewers bought it for mothers or daughters, citing its easy, foolproof application as ideal for less makeup-savvy users.
Natural, wearable shade range
Buyers seeking a subtle, non-harsh brow look purchased it after finding other brands too dark or artificial-looking.
