Wasting products is history now obviously because, it doesn't soak up your product! The foundation needed is literally just half the amount compared to directly using brush or sponge. Using it will take some getting used to, because its a whole new thing to apply your foundation with. The final blending can always be finished with a brush or usual sponge, that means washing the brush or the sponge will be minimized and they will last a whole lot longer. It is ideal for people who don't like messy fingers during makeup. AND I bet you can imagine cleaning THIS APPLICATOR will literally take no more effort than rubbing it with a little soap and rinsing with some luke warm water. If you are a professional makeup artist, can you imagine how exciting it is that you can use it on one client/model, clean it with a makeup remover and sanitizing spray, and then you can use it on another client/model immediately just like that? Throwing away disposable sponge can totally be minimized!!!
