Celebrity/influencer endorsement
Numerous reviewers, particularly in Japanese and Korean markets, cite seeing K-pop star Taeyeon or beauty YouTubers/Instagrammers use or recommend the tool as their reason for purchase.
Solving cream/liquid blush application problems
Many buyers specifically sought a silicone tool because applying cream, liquid, or balm blush with fingers or a sponge felt messy or produced uneven, blotchy results.
Travel and touch-up convenience
The dual caps and compact size are frequently mentioned as the deciding factor for buying it as a travel or on-the-go touch-up tool.
Affordable price/value versus alternatives
Several reviewers compare it favorably to pricier Western dual brushes (e.g., Glossier), noting it is more compact and cheaper while performing similarly.
Repurchase/backup buying
A number of repeat customers bought a second unit to keep one at home and one in their travel pouch, or restocked after their first one wore out.
