Since I've been seeing a lot of Pinay beauty bloggers and Youtubers use this brush, I decided to try it myself and see what the fuss is all about. This brush wasn't that hard to get a hold of since it's readily available in most Watsons stores all over the country.
The Marionnaud N38 Slanted Eyeline & Eyebrows Double Side Brush, as the name suggests, is a dual ended brush. One side is an angled brush with synthetic fibers and the other side is a spoolie. I quite like the size of this brush: it isn't too long that it doesn't fit in your makeup bag nor isn't too short that you have a hard time gripping it. I appreciate the plastic cap for the angled side but I would've preferred an actual cap, not just a plastic one that I can easily misplace. The brush comes in a sturdy plastic container with a Ziplock-type of zipper that can double as its pouch. I really like that Marionnaud brushes are packaged like this. Brush with its own pouch and not just a disposable bag? I approve.

Now let's get to the angled brush side. As you can see, the brush is thin, almost similar to the MAC 266 but a little thicker than the EcoTools Angled Eyeliner brush. As it's synthetic, it feels a little slippery and a little plastic-y. It has good amount of width as well. As for the spoolie, it's the usual type.

I tested this brush with a powder product and, surprise surprise, I was a little wobbly. It's such a new experience! It was my first time using a thin synthetic brush so I had to really feel the brush. With powder, the brush feels a little slippery. I guess I'm just used to brushes with natural bristles that I'm really looking for that 'grit'. A little roughness that works the powder on your brows and skin. The N38 felt slippery and that made me go back a few times to the sparse areas of my brows. BUT I sort of like the slippery feel in a way because it prevents me from putting too much pigment on my brows. It controls application so you get to define the brows slowly instead of brushing a lot of product in one go.

One thing I really like with this brush is it gives me a precise line under the brows. I get to line the bottom/root area of the brows cleanly in one stroke. It also helps a lot with filling the inside areas of the brows. Aside from the slippery feel, I also noticed that this brush doesn't really hold product. Brushes with natural bristles hold/store product even after application but with this, I feel like the powders just slide off. I had to dip it on the brow powder pan after each fill because there are no leftover powders on it. A little tedious to use but I guess the end results are pretty good.

Overall, I'm okay with it. I've yet to try it with a cream/gel/pomade which I think will pair better with this brush. It's a little slippery when used with powder so I really think it'll work well with something with a thick formula. I don't think I'll use this for lining the eyes, though, since I have my EcoTools brush for that. It's a little pricey (129php) but think of it this way: you're paying for two brushes in here. When you buy a brush and a spoolie separately, I think it'll add up to the same amount, if not, more. If this was a little gritty, it would've been perfect. But that's just personal preference and shouldn't hinder you from trying it out yourself. :)
