I got the under eye concealer brush because it’s pretty unique looking, and I have seen other people using it (I think it was Theresa Is Dead)? I have been enjoying it very much. It’s a bit better designed than the BK Beauty kitten paw one that I also like for the under eye. The sponge I threw in my cart on a whim, however, is an unexpected favorite. It has a feeling of almost being gelatinous when it’s wet - very bouncy and lots of give but really works well. It’s very fine and expands a lot when wet. I would buy more of these if I didn’t already have a thousand sponges!!!!! :)
