Repurchase loyalty
An unusually high number of reviewers state this is their 3rd, 5th, or even 10th repurchase, indicating strong brand and formula loyalty.
Reputation for smudge/waterproof performance
Many buyers explicitly sought out this pencil after failing with other 'waterproof' liners, citing CLIO's reputation as genuinely long-wearing.
Beginner-friendly application
Several reviews mention buying it specifically because it's easy for makeup beginners or those who struggle with liquid liner to control.
Shade variety collection
Buyers often purchase multiple shades (Ash Brown, Rose, Vanilla Beige, Coral, Black) for different looks like aegyo-sal, waterline, or outer corner definition.
Value/bundle promotions
Comments referencing 1+1 deals, discounts, and favorable overseas shipping cost suggest promotional pricing drives purchase decisions.
