Brand/artist reputation
Several reviewers cite watching Jungsaemmool's own makeup tutorials or brand videos (including a makeover for a model with acne scars) as the reason they sought out and purchased the puff.
Solving small-area application problems
Buyers commonly bought it specifically to solve the issue of standard-size puffs being too large for under-eye, nose, and mouth-corner areas.
Cushion foundation compatibility
Some reviewers purchased it because their JUNGSAEMMOOL or other cushion foundation puff didn't reach nose/corner areas well, and this smaller puff fit that gap.
Repurchase/refill
Multiple reviews mention this being a second or repeat purchase, or buying it as a mini-cushion/puff replacement after liking the brand's other puffs.
Curiosity from positive word-of-mouth
Several buyers say they purchased after hearing 'many good reviews' online, indicating social proof drives conversion despite the niche use case.
