Trend-driven 'over-lip' technique
Many buyers purchased specifically to recreate the popular blurred, overlined lip look, valuing that the product combines a liner and a shading pencil in one tool.
Affordable price / frequent sales
Numerous reviews (especially Japanese) mention buying repeatedly because the item goes on deep discount ('bug price'), making it a low-risk, high-value purchase.
Celebrity/influencer association
Several reviewers cite hearing that Le Sserafim's Yunjin uses the product as a reason for trying it.
Repurchase after satisfaction
A large share of reviews are repeat buyers who bought a second, third, or even fourth unit or ordered additional shades after a good first experience.
Dual-function convenience
Buyers appreciated getting a lip liner and a contour/shading pencil in a single product, seeing it as time- and money-saving versus buying separate items.
