The E25 blending brush was free with my purchase & I'm really glad they sent me this one. I use it to apply darker shades to my crease. It applies easily & blends all in one. The only downside is after washing this brush the hairs seemed to go a little crazy, but overall It still works great.
The E45 is the Small tapered blending brush. I use this to blend my lid color into my crease & then to blend my highlight color. This brush is truly amazing! Works way better than the one I had from ELF. Held up to a wash just find & still looks brand new.
The E70 Medium angled shading works great for the browbone/highlighting. I love that this brush picks up enough product to get the job done. Held up to a washing.
The E55 shading brush is great for applying color to the lid. Picks up enough color where you can fill your entire lid with just one swipe, unless your going for a darker/heavier look. I also use this to aad darker shadow to my crease. Works great at fitting perfectly into my crease & also the outer "v" area. Held up to a washing.
Overall I'm very satisfied with these brushes & can see the difference that quality brushes make in the application of makeup.
Can you believe a couple years ago I didn't think I needed brushes, I would just use those sponges that came with the shadows. I've come along way!
