when i got this cushion, i was worried at first bc i didn't realized it was a refill (i don't have the actual product). but now i absolutely love this product! i'm applying it with my regular foundation brush, idk if it's the best way since it's a cushion, but it works. the coverage is great, and it matches my skin colour better than the missha m perfect cover bb cream, (that is a little too grey). i absolutely recommend this!
