The bristles are firm and great. This is exactly the brush I wanted. I bought it to do tightline eyeliner.

Flat multi brush

This brush is thin and small, making it very versatile. I bought it as a replacement for the Picasso 722 which broke, and I found it to be quite similar when used. The vertical length is shorter, and the horizontal length is just a bit longer than the Picasso 722 brush.

It does feel a bit stiff, which might feel irritating to some, but if you use it gently, that issue is resolved. Overall, I'm satisfied.

Its small and thin design makes it really useful for drawing eyeliner with shadow. I hope it doesn't get discontinued because it's also great for shading the aegyo-sal area.
I plan to repurchase if it breaks. I like it.

Hmm... The straight shape makes it comfortable to use. If you're a beginner, it helps you draw thin lines well.

The brush is flat and thin, making it easy to create detailed looks.

I bought the liner brush and have been using it, and I was so satisfied that I purchased the flat brush as well!

I really, really love this. I need to stock up on a few more.

I bought this to draw lines with eyeshadow. It's flat, so it feels very comfortable and I think I'll use it well! The price is good, and I like the unique design!!

I ordered this because I wanted to draw lines with eyeshadow! It's thin and seems like it will draw well, so I really like it. I think I've bought a lot of good brushes from Hemeko hehe. Highly recommend!

It's definitely a bit smaller, so it draws very precisely. It's great for under the eyes and lining the eyes.

Thin and sturdy. Exactly the brush I was looking for! There are many thin and small brushes on the market, but they often lack strength or the bristles splay out. This one is strong!! I plan to use it as an eyeshadow detail brush or an eyeliner brush. This is definitely an item I'll use a lot~~~

I bought this to apply eyeliner more comfortably~

I recently started doing tightlining makeup, so I bought this brush. After using Picasso, I got curious and decided to try the short bristle one too!!

I haven't used it yet, but I bought it because of the good reviews. It would be great if it came with a brush cover. Other brushes came with covers, but this one doesn't, so it's inconvenient because dust sticks to it when storing.

Wow, this is the brush I reach for the most out of all my brushes! It's amazing for lining!!

I always draw my eyeliner with shadow, so it was hard to make the tail natural and thin, but this brush is really thin and firm, so it glides on easily!!

If I had to mention a downside, it’s not very soft; it’s a bit rough and stiff... It might hurt if you use it under your eyes or for other purposesㅠㅠ

I have no idea where else to use it besides drawing the tail of the eye. I bought it cheaply with coupons and expiring points, but I probably wouldn’t buy it at full price..!? 

But on the other hand, super soft brushes don’t pick up shadow well and tend to shed powder easily, so maybe it’s good that this one is a bit stiff.

Lately, I've been really into filling in my waterline, and since I didn't have the right brush, I decided to buy this one. It's dense and firm, making it perfect for filling in the waterline. I plan to take good care of it to avoid shedding or clumping. It's also great for lining because it's thin, firm, and draws very smoothly. It's even good for creating a wing with your nail! I will definitely repurchase 10000000000%~!!! If there are big sales, I'd stock up without hesitation. There's also a wider version of this brush, which I plan to buy next! Thank you for making such a great brush.

The bristles are short and resilient, making it easy to extend the eyeliner smoothly.

I don’t like drawing eyeliner in a noticeable way, and I prefer using gel eyeliner only on the waterline. I was looking for a thin and short brush, and this one is perfect.

I had this in my cart for a while debating whether to buy it, but when TheBalm went on sale, I purchased it right away!! I bought it together with the Slim Edge brush and here are comparison photos. The one on the left is the Flat Multi, and the one on the right is the Slim Edge!!

It's perfect for applying eyeliner! The shape fits just right. It stings a bit when used on the under eye..ㅠㅜ
