I saw this on sale for $5 I think on Ulta's website when I was placing my order about a month or so ago. You have to spend a certain amount to get free shipping, I will always spend that amount. I hate spending money on shipping, and I will always find something else to buy lol.
I usually just use a tissue to wipe my eyeshadow brushes between colors, but I thought this was pretty cool. So, I decided to give it a shot.
It does a pretty good job at removing the eyeshadow color I used before using the next one. If you look at the photos above. The top right is the sponge unused, the bottom left is me about to use it, and the bottom right is after. You can clearly see the pigment on the black sponge, and the color has been removed well enough from the brush to use a different color.
I went bold and used it with black eyeshadow before switching to a lighter color, and I was impressed by how well it removed the color. Granted, the brushes are stained (these are my Tarte Mermaid Brushes that I haven't reviewed yet but need to), but the bulk of the powder is removed.
Honestly, I can't see using this with any other brush aside from eye makeup brushes. It's a decent size, but I wouldn't use a blush then foundation on the same brush. Clean up seems easy too; once one side is used, flip it over, then, when both sides are used.. simply wash it out. It's really easy to use, easy to clean, and it's portable and convenient.
Overall, I recommend it. It definitely wasn't a bad buy for $5!
