Influencer/KOL recommendations
Multiple reviewers explicitly say they bought a specific shade after seeing it recommended by a Taiwanese, Korean, or Instagram beauty influencer/YouTuber.
Wide, novel shade range
The 8-color lineup (including unusual tones like lemon, green 'seashell', and rose gold) attracts buyers looking for a shade that matches their personal color type (e.g., spring/warm, cool olive) or something different from typical white/pink highlighters.
Repeat purchase / shade collecting
Several long-time espoir highlighter fans say this is their 3rd-5th shade purchased from the line and that they intend to collect all colors.
Sales and bundled brush value
Many reviewers cite discount/sale pricing and the free applicator brush as a reason for purchase, describing it as cheap and good value versus high-end brand highlighters.
Gifting
At least one reviewer purchased it as a birthday gift for a friend, noting the recipient (a 'deep autumn' color type) loved it.
