Social media / influencer buzz
Multiple Japanese and English reviewers specifically mention seeing the product go viral on Twitter/X or being recommended by beauty bloggers before purchasing.
Repeat purchase / brand loyalty
A large share of reviews explicitly state this is a repurchase ("リピート", "回購"), with some buyers owning 3-5+ shades already.
Wide 13-shade range for shade matching
Buyers frequently mention picking new colors to better match undertone (yellow vs. blue undertone) or to build a full collection after liking one shade.
Multi-purpose versatility
Reviewers cite the ability to use one product for aegyo-sal, triangle zone, mucosa line, eyebrows, and even lip lining as a reason to buy over single-purpose liners.
Promotions and price-value during sales events
Several reviews mention buying during discount events (メガ割, coupons, bundle deals) because it was cheaper than usual retail or Qoo10 price.
