Influencer/YouTube recommendation
Multiple reviewers explicitly say they bought the pencil after seeing it recommended by Korean beauty YouTubers or TikTok creators who carry it as an everyday staple.
Repurchase/brand loyalty
A large share of reviews are repeat or multiple purchases, with buyers collecting several shades after being satisfied with a first pencil.
Natural 'my lips but better' color match
Buyers frequently purchase specifically to find a nude/rose shade that mimics or slightly enhances their own natural lip color for the popular Korean overlip look.
Promotions/value bundling
Several reviews mention buying during Olive Young sales or promo events, citing good value and fast delivery as a purchase driver.
Reputation of Banila Co / K-beauty trend alignment
Some reviewers say they trust the brand generally ('you can't go wrong with Banila Co') or wanted to replicate a trending Korean soft-blur lip makeup style.
