Reputation for long-wear formula
Many buyers purchased specifically because they heard the 'lineproof'/12-hour version lasts significantly longer than the brand's regular lip pencil, seeking a product that survives eating and drinking.
Repurchase/brand loyalty
Numerous reviewers already owned other Heart Percent lip pencils and bought additional shades or the upgraded lineproof version because they trusted the brand's performance.
Influencer/trend recommendation
Reviewers cited an 'oiseau' recommendation from a Japanese beauty YouTuber (Odagiri Hiro) and general online buzz/trending 'overlip' makeup technique as reasons to try it.
Bundled mini lip gloss value
The set including a complimentary mini lip tint/gloss was frequently mentioned as a bonus that added perceived value and prompted purchase.
Gifting
Some reviewers mentioned buying multiple colors to give to friends, citing the cute packaging and reliable performance as gift-worthy qualities.
