Repeat purchase / Brand loyalty
Multiple consumers explicitly mention buying it again after prior successful use ('On my second one,' 'リニューアル前から使ってます,' 'I've tried many brands of eye pencils, but personally, this product fits the best'). Strong indication of satisfied customer retention.
Social media / Influencer-driven discovery
At least one reviewer mentions purchasing after watching an Instagram ad, and the product shows high engagement on TikTok and Instagram platforms. Korean beauty influencer endorsement likely drives international awareness.
Waterproof / longevity claims
The 'Double Effect Waterproof' claim is the primary purchase driver. Consumers explicitly seek this product for its reputation as an exceptionally durable, non-smudging eyeliner suitable for long wear and humid conditions.
Attractive color range and quality reputation
Reviewers note appealing shade options (matte brown, cinnamon mocha, black) and comment that the product delivers on color promise. Korean cosmetics brand prestige motivates purchase among international buyers.
Price value and promotion access
Several reviewers mention buying during sales ('セールでとっても安かった,' 'Easy to use it, It's a great value for the price'), and note stock availability on OliverYoung when brand's own shop is depleted.
