1+1 value bundle
Reviewers repeatedly cite the '2-for-1' set (sometimes with a bonus tweezer or mini mascara) as extremely cheap compared to Qoo10/other retailers, driving impulse and stock-up purchases.
Word of mouth / influencer & SNS hype
Many buyers say they purchased after seeing YouTubers, Instagram/TikTok creators, or Korean makeup artists use it, or because it is described as a 'national' Korean mascara.
Repurchase / loyalty
A large share of reviews are explicit repurchases, with some users on their 4th or 5th tube, indicating strong brand and formula loyalty over other mascaras tried.
Solves straight/stubborn lash curl-drop problem
Reviewers with straight Asian lashes specifically say they bought it after failing with other 'curl keep' formulas and finding this one to actually hold curl all day.
Cute limited-edition packaging
Several reviewers admit to a 'packaging purchase' (パケ買い), especially for the Princess Edition, buying it partly for the visual appeal even when they already had stock.
