Ultra-thin, precise tip
Reviewers repeatedly cite the skinny pencil tip as the main draw, saying it lets them draw individual hair-like strokes and fix mistakes easily, unlike thicker competitor pencils.
Natural, hard-to-find shade range
Many buyers specifically sought the cool-toned ash/gray-brown or taupe shades that flatter black or dark brown hair and said similar tones are unavailable from domestic Japanese or Western brands.
Affordable price / high value
Numerous reviews highlight the low price relative to quality, often noting a built-in spoolie brush is rare at this price point, driving perceived cost-performance ("コスパ").
Repeat purchase / loyalty
A very large share of reviews mention buying their 2nd-7th+ tube, describing it as a 'holy grail' or must-have staple they restock repeatedly.
Influencer and word-of-mouth recommendation
Some buyers mention discovering the product via YouTubers, makeup artists, or SNS posts, or through good online reviews before purchasing.
