Cute packaging (パケ買い)
An extremely high number of reviewers explicitly say they bought the item mainly because of the adorable, magical-girl-style compact packaging, even before trying the formula.
Bonus hand mirror
Many buyers state they purchased primarily for the included heart-shaped hand mirror, which they describe as cute, convenient and 'worth the price alone.'
Brand loyalty to Glint highlighters
Repeat customers note they already collect Glint highlighters and trust the brand's texture and finish quality from prior purchases.
Limited/collab edition hype
Reviewers mention learning about the 'planned/collab set' via SNS or Olive Young promotions and buying it for its limited-edition appeal, sometimes confused it was more exclusive than the regular line.
Gifting
Several reviews describe buying the set as a birthday or friend/family gift, citing the pretty packaging and mirror as ideal gift-worthy elements.
