I personally believe this is a must have for any beauty bag which contains foundations - mousse or liquid!! This pear shaped latex sponge is amazing, it doesn't absorb any of the make up.. A tiny drop is used and dotted all over the face and neck, then blended with this sponge for a smooth, seamless and natural finish... Cleaning is pretty easy and effortless, damp the sponge - apply a drop of shampoo - rinse - squeeze, then it's just like new again.. Natural yet full coverage looks obtained so easily :)
