Look what I found! There Their own description: I do't know if it's really that good, but I'm getting one.
I bought a knockoff one and I hate it so much. You cannot blend with it at all. Foundation just sits on top of the skin. So for a while I was applying with the silisponge and then blending with the beauty blender but theres no difference between applying with your fingers.
I haven't tried it but I don't like the idea. The beauty blender makes my foundation look perfect already
