Influencer/social media trend
Many reviewers cite seeing the product used by Korean idols, YouTubers, or on Instagram/TikTok/X (e.g. 'ALLDAYPROJECTのヨンソが使ってて真似した', 'Xで見て購入'), driving trial purchases.
Repurchase and loyalty
A large share of reviews mention this being their second or third purchase, or collecting multiple shades, indicating strong repeat-purchase behavior.
Affordable price / promotions
Reviewers frequently mention buying during sales or citing 'good CP值' (value for money), 1+1 deals, and low price as a purchase driver.
Ease for makeup beginners
Several reviews describe it as beginner-friendly for creating the aegyo-sal look without skill, lowering the barrier to purchase for first-time users.
All-in-one convenience
The dual-ended format combining shadow/contour and highlighter/concealer in one pencil is repeatedly cited as a reason to buy over separate products.
