Merje Let's Fixing Pen Eyeliner Brownie

What it is

The Merje Let’s Fixing Pen Eyeliner Brownie is a budget pen-style liquid eyeliner with a slender, firm-bristled applicator. The formula deposits a dark neutral brown with minimal skipping and sets quickly without heavy tugging. It sits between temporary and long-wearing—easier to remove than heavy-set formulas, but not effortless to wash away. The brownie shade is versatile for both definition and softer lining.

What Korean reviewers say

Daiso shoppers rate it 4.8/5 across 1,635 reviews, signaling strong approval within the budget category. Korean consumer feedback emphasizes exceptional value; many reviewers compare it to eyeliners costing three to five times more and report repurchasing it despite owning pricier alternatives. The standout praise centers on the thin brush tip for precision and consistent color payoff. However, longevity has real limits. Reviewers clarified that the formula resists smudging initially but is not truly waterproof—some experienced gradual fading or minor fallout under the eye by evening, particularly those with oily skin. Packaging durability emerged as a genuine flaw; multiple users flagged broken caps and occasional leakage. The tip also gradually dries and can separate into powdery texture with time.

Bottom line

At $2.22, the Merje Let’s Fixing Pen Eyeliner Brownie delivers usable quality for casual, everyday wear. It is a smart pick for beginners learning precision lining or anyone prioritizing affordability over all-day performance. If you need waterproof staying power for humid climates or very oily skin, or plan to rely on one eyeliner for heavy wear, the durability trade-offs make it less reliable. Best suited for light-to-moderate use and dry-to-normal lids.
