Influencer/celebrity exposure
Several reviewers mention seeing K-pop idols, YouTubers, or Instagram/TikTok influencers using ceramic massagers before buying, and one explicitly references a TWICE member using a similar item.
Repurchase of the brand's face gua sha line
Many buyers already owned Fillimilli's purple face gua sha and purchased the body version because they trusted the brand's material quality.
Value versus competitors
Multiple reviews say this ceramic massager is cheaper than other body massagers sold on Amazon or in-store, making it an attractive entry point into gua sha/body massage tools.
Gifting
Reviewers frequently bought a second unit for their mother, boyfriend, husband, or friend after trying it themselves, indicating strong gift-market appeal.
Beauty box inclusion
A notable number of reviews came from Olive Young 'May Box' or beauty subscription box recipients who tried the product passively and then rated it positively, suggesting sampling drives conversion.
