Brand loyalty / repeat collecting
Numerous reviewers say they are 'collecting all 3CE palettes' or repurchasing a color they previously hit pan on, indicating strong brand equity and repeat-purchase behavior.
Influencer and word-of-mouth recommendation
Several buyers cite YouTube/beauty influencer videos (e.g., 'Minsco', 'Happyrim') or general hype ('many people recommended this') as the reason for purchase.
Unique, hard-to-find color combinations
Reviewers frequently note the palette offers shade combos (blue, green, ash-mauve) not found in other brands, driving purchase for variety-seekers.
Sale/discount pricing and coupons
Many Japanese and Chinese-language reviews mention buying during a sale or with a coupon, citing high cost-performance (CP値) as a purchase trigger.
Restocking a finished favorite
Some reviewers explicitly state they repurchased because they were running low on a shade they already loved, showing genuine consumable repurchase demand.
