Thanks Natalie for your review!
"I have just about every konjac sponge you can have, the charcoal one was the last one I needed to get. Save the best for last they say, this one is amazing! To get the best from this sponge, you must let it get soft in warmer water. I like to get warm-hot water on my face to open the pores, for the best cleaning of the skin. It leaves my face feeling amazing." - Natalie H. from Amazon.com. http://blog.nataliemadeit.com
