Erase, blend and soften! The extra-fine texture of these easy-to-hold sponges turns the tiniest dot of foundation into sheer, silky, flawless coverage. Use your sponge wedges like erasers to blend away any excess concealer. AV TIP: For a professional makeup application, never use your fingers, and foundation brushes are just not professional and may cause streaks. Blending is very important to achieve a flawless finish with foundation.
