For makeup [SEP] I don't often wear cover-up but when I do, a good sponge can really help with the application. The sponge can get into the crevices better than your fingertip can and is much gentler to use around your delicate eye area. I've found cleaning them is somewhat of a chore, but you need to keep them clean. I rinsed mine thoroughly and let it air-dry. This 10-pack is a good value and will last awhile.
