Reputation for gentleness/low irritation
Many buyers cite the brand's mild, non-irritating formula as the reason for purchase, especially those with sensitive, atopic, or acne-prone skin seeking a safe first-toner option.
Repurchase/loyalty
A very large share of reviews explicitly mention repurchasing (2nd–6th bottle), indicating strong repeat-buy behavior driven by satisfaction rather than novelty.
Bonus keyring/plush novelty
Multiple reviewers say they bought this edition specifically for the cute Nunmeongi keyring or plush, treating it as a gift or collectible alongside the skincare.
Word-of-mouth/hype and social media
Several reviewers reference having heard 'a lot of things' or seeing it trending on SNS/TikTok before trying it, suggesting influencer and viral exposure drives trial.
Value/size (double pack)
Reviewers highlight the large double-pack volume and travel-size mini as good value for money, appealing to price-conscious bulk buyers.
