Bundled brush adds value
Many reviewers explicitly bought it because it comes with a free contour brush (and sometimes a bonus blush/highlighter), making it feel like a bargain versus buying a brush separately.
Rare true cool-tone shade
Several buyers say they purchased because it's hard to find a genuinely cool-toned contour elsewhere, and this product finally met that need.
Influencer/YouTuber recommendation
Multiple Japanese and Korean reviewers cite specific YouTubers/makeup artists (e.g., 小田切ヒロ, 夢月, a Single's Inferno cast member's tutorial) as the reason they tried the product.
Repurchase/loyalty
A large number of reviews are explicit repeat orders ('3rd time', '5th palette'), indicating strong repurchase intent once a buyer finds their matching shade.
Affordable price and large size
Reviewers frequently mention it being cheap for the amount of product, calling it good value especially during sales.
