Dual functionality and convenience
Many consumers purchased this specifically for its two-in-one design, choosing it over alternative single-brush options. The ability to carry one tool instead of two brushes made it particularly attractive for travel and everyday portability.
Hygiene and cleanliness improvement
Multiple reviews cite switching from finger application to brush application as a primary motivation, with consumers appreciating the more sanitary application method and ease of cleaning.
Specific use case—gradient and smudged lip looks
Buyers sought this product to achieve blurred, diffused, or gradient lip effects that are popular in Korean beauty trends. Reviews mention intentional purchases to create softer, 'fluffy' lip appearances.
Comparison shopping and product features
Some consumers explicitly chose this over competitors because of the cap design and the combination of silicone and bristle ends, indicating they were deliberate in selecting features not available elsewhere.
