The amount of liquid or cream products needed is about half the amount compared to directly using a brush or sponge. Spreading product with it will take some getting used to, final blending can always be finished with an oval brush or usual sponge (for example beauty blender), that means washing the oval 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 lukewarm 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!
How to use:
Take the littlest amount of cream/liquid product and go in circular motions or back and forth to spread, until it stops spreading further.
Tap repeatedly to blend and settle, pay attention to edges (jawlines, hairlines, around the eyes). Hold the sides and fold to create a "point" for detail and point applications.
