I know the description says mini sponge but this sponge is so super tiny that it only serves few purposes. It can be useful for the under eye area which would benefit from such a small sponge. However, if you're looking for a decent size sponge for foundation, this is certainly not it.
This is a pretty good sponge. It's a little stiff which takes a minute to get used to working with. But after figuring it out, it lays concealer nicely. It's the perfect size for the inner corners of the eye and leaves a smooth finish.
