Affordable price point
Many reviewers explicitly cite the low cost relative to brush quality as a key reason for purchase, calling it 'good value' or 'reasonable price' compared to other brushes they own.
Dual-ended convenience
Buyers frequently chose it because one tool offers two brush sizes (a flat/wide end and a fine point), saving space in makeup bags and eliminating the need to buy two separate brushes.
Brand trust / repeat purchase
Several reviewers mention repurchasing because they already trust Fillimilli's brush quality, or bought it as a replacement/backup for an existing brush ('washing spare' or restock).
Influencer/social media recommendation
A number of reviews mention discovering the product via TikTok or YouTuber recommendations before trying it themselves.
Beginner-friendly tool for concealer application
Several first-time concealer-brush buyers purchased it specifically because they were previously blending with fingers and wanted a more precise, beginner-accessible tool.
