    this is amazing for picking up shimmer shadows because it has stiffer bristles!

    Great brush

    Posted by S on Jul 31st 2023

    I have used the W23 brush for years and it is great for applying nearly any shadow, even stubborn or tricky formulas. So now I picked up this one to use on small eyes. Same great shape & bristles + smaller size = perfect. And if ESUM wants to make an even smaller version, I would pick that one up too. These are great.

    Beautiful Brush

    This is a great brush. Super soft and does a fantastic job picking up and applying shadows. I've used it for Natasha Denona cream to powder as well as metallic shades and it works as well as finger application. The size and shape are perfect for laying down product in the inner corner as well as a cut crease.

    This is the second of the two brushes I recently purchased. I saw this on a YT-influencer video. It picks up and puts down shimmers and metallics beautifully. It is great for those with smaller eye space, hooded eyes. Fantastic for inner corner area. Love it! A must have.

    I picked up 5 of the Esume Brushes. I was eager to try the line, and it was money well spent. Each one works better than I expected and in spite of owning many other professional/high end brushes, I have not been able to stop using these since they arrived. They are a joy to work with, clean up beautifully, and I look forward to picking up more to add to my kit, and for my own personal use. The W21 is a beautifully functional brush. I've used it for creams and powders and it puts product exactly where you want it.. A great brush for multiple uses..

    For any eyeshadow that has ever been patchy

    You have met your match. Eyeshadows that I disliked I now love. Using brushes from ESUM have taught me a lot about how proper application can make a world of difference.

    Great multi use brush

    Posted by Shell on Mar 26th 2018

    I've never used Esum brushes before & decided to start small. The quality of this brush is excellent. The hairs are firm but not stiff, the brush is soft & the length of it makes it good for many applications. You could use to blend lower lashline, smudge liner, apply & blend concealer. And of course pack on eyeshadow. I recommend this brush, it's a good introduction to the Esum line & if this brush is an indication of the quality I can expect from Esum, I plan on purchasing more brushes from them asap.
