Brand loyalty / repurchase
Many reviewers explicitly state they are longtime fwee fans who collect multiple lip products or colors and repurchase because previous releases satisfied them.
Cute packaging and concept
A large share of reviews cite the adorable bottle design, gradient packaging, and 'Vanilla Universe' concept as a key reason for purchase, often discovered via SNS/social media.
Bundled mini latte gloss bonus
The included mini gloss (marbled latte-colored bonus) is repeatedly named as a strong incentive to buy, with several reviewers wishing it were sold standalone.
Sale/discount pricing
Several Japanese and Chinese reviewers mention buying during promotional sales periods for better value, citing good price-to-quality ratio (CP値).
Shade variety for skin tone matching
Reviewers across warm and cool undertones note they found a suitable shade among the 27 colors, appealing to a broad customer base.
