The first time I bought it, it released a large amount shortly before finishing, causing my eye to get smudged. However, it had a nice brush overall and I didn't pay attention. The second time, the lid had some issue, resulting in it not closing properly and drying out. I wouldn't buy it again.

The first time I tried this particular product, I thought it was defective because after three uses it didn't produce any color, so I bought it again, this time from a different store. Same thing happened. Especially the brown eyeliner is even worse, it produces a color that is barely visible, almost like a shadow. While it is very cheap, if someone tries k-beauty or j-beauty products that have the same price but decent quality, they won't go back to drugstore products sold here (of course, there are always exceptions).

Very bad, it's like it doesn't produce color on the brush, it creates a very faint line as if it's at the end, you apply it, reapply it, and in the end it smudges.

At first, when I bought it, they marketed it as a very good product. After one application, it didn't produce any color for some reason. I shook it countless times and pressed it on a surface, but still no result. Just disappointment and wasted money. It would have been better if I had bought from another more affordable company.

I was very disappointed.
As soon as I opened it, I made a line and then it came out blurry, like it would at the edges. I think it has a very matte formula and it dries directly on the brush.
When I used it on my eye, it smudged a lot. It had no precision at all.
Also, when I tried to go over it again, it would remove what I had already done.
I had a lot of difficulty removing it. The hand that I made test lines with is still black two days later.
I really don't understand how it can apply so poorly and at the same time not come off.
Nevertheless, I gave it another chance the next day and used it for work. By the time I arrived, it had already left a mark on my upper eyelid as I have hooded eyes and it can happen when the product is still wet. This specific one dries very quickly though, so I believe it's the formula's fault and not any rush.
It's really a shame, as another girl also said. It's a waste of money.

Although it is not expensive, I cry my money.
I started to draw a line and after a while it was difficult to remove the product.
I managed with great difficulty.
Immediately, the color transferred and my eyelid got smudged, it didn't last at all in general.
I do not recommend it

I have tried many... ideal for a thin line... perfectly stable until late at night... it doesn't smudge... it doesn't leave traces... the only negative is that the hairs get caught in the cap and some have bent, but they don't bother with the application..
I will come back for feedback... in the end, the hairs are getting worse and worse... and also, when I open the product, it drips several drops,... so when you store it, either horizontally or with the cap facing upwards

It is amazing, it colors perfectly. Its size is like a pencil, meaning very small which makes it ideal for a small bag. Intense color and perfect design. ⭐⭐⭐⭐⭐

It is very good, I am doing Eyeliner and Makeup for the first time in general, so I don't have high expectations yet, but it works perfectly.

Excellent eyeliner! Easy to apply, without the tip drying out during use, as often happens with markers. Intense black color that lasts for many hours without fading, despite the heat and my oily skin. It does not smudge or easily come off, but I suppose that is the price for its long-lasting formula. The price is also excellent.
Update: I bought it for the third time and it seems to be defective: the ink runs from the tip, as soon as I open it, it splatters, stains my hands, and everything around. Also, I reconsider its stability. In conditions of high heat and humidity, combined with wearing a mask, it does not last for many hours.
