I love this brush so much that I bought one for my blush and foundation and the other for my bronzer and contour. The dense side is great at packing on product precisely, and the more fluffy side blends things out like a dream. My only minor complaint is that once in a blue moon, it can feel the slightest prickly.

100000% recommended!! 🤍✨ The F4 Brush by Mario is hands down one of the best foundation brushes I’ve ever used. It blends foundation effortlessly, gives you a smooth, airbrushed finish, and doesn’t leave streaks when it’s clean. It also works beautifully with dewy formulas! My only tip: keep it clean! Once too much product starts building up on the bristles, it can begin leaving lines and make the application less seamless. I wash mine regularly, and it performs like new every time. Definitely worth the investment! 💖🙌

An employee recommended this brush and I wasn't convinced, but thought I'd give it a try. WOW. It quickly became my absolute go-to brush for my bronzer and I want another for blush and a few backups to keep for the rotation as I clean brushes. I've used this brush for a couple months now, I've washed it at least weekly with no issues with it falling apart. It blends beautifully and works quickly and effortlessly. No streaks or patchiness either. This, along with my BK Beauty, and NikkiLa Rose Brushes are all I reach for now. I bought an Amazon dup e and the ELF dup e, and neither work as well. The ELF does come close, but it definitely doesn't feel as high quality, nor the brushes as dense as the MBM. The Amazon dup e is trash. If you're thinking about it, save your money. I read lots of reviews before I buy anything, so hopefully this is helpful for some of you. Purchased with my own money and I'm not a fake review.

Pleased with this brush. Smooth application of foundation. No lines and blends well.

Cannot live without this multi use brush!!! It works so well at blending creams and powders. I’ll purchase again and again…

has helped my makeup look so much better and my bronzer looks better. i used a brush before that made my powder bronzer look kind of muddy but this mario one makes my makeup look so amazing!

Best makeup brush I own, worth every penny. My only regret is not buying it sooner

The hype is real! I have over 200 high end brushes (😅) and this is genuinely one of my favorites - so much so I bought 4 for myself and purchased many others as gifts to my fellow makeup addict friends.

This is the best brush on the market, in my opinion. It is great for everything.

My go to brush. Blend out creams and powder beautifully. I’m glad I pulled the trigger on this one. Worth it!
