Social media discovery
Several reviewers said they bought the product after seeing it advertised or demonstrated on TikTok or Instagram, indicating strong influencer/algorithm-driven demand.
Novel hygiene concept
Many buyers purchased out of curiosity because they had never seen a dedicated piercing-hole cleaning product before, especially in markets like Japan where such items are rare.
Friend/family recommendation
A number of reviews mention buying because a friend or family member (sometimes with many piercings) recommended it and reported good results.
Repurchase/loyalty
A notable share of reviews are explicit repurchases, citing satisfaction with previous use and wanting to keep a steady supply, including switching to the thinner stick variant.
Gift purchases
Some customers bought the set for their mother, daughter, or friend, suggesting appeal as a low-cost, easy-to-explain gift for pierced-ear owners.
