Hey, I want to share my impressions of the Konjac sponge.
Price: $5.99
At the store where I bought it, the sponge was in three different colors: white, green and black. I opted for the black one as my skin is acne prone. I also had sponges of different colors that I used a few months ago.
The old and the new ones
Packaging
The packaging inside was all wet (so the sponge will not to dry out while transporting). There’s a handy string to air-dry the sponge, which is very important, otherwise, the sponge will be a house for bacteria.
I keep it in my bathroom, I know it isn’t the driest place in my house, but I have no other place.
The sponge dries out totally in about 24 hours. When it’s dry, it’s half the size smaller to when it’s wet. When wet, the sponge has very soft, gentle and pleasant to the touch texture.

Comparison of the sizes
I have found two ways to use this sponge:
apply a tad of face cleanser on the middle of the sponge, foam it and massage my face.
massage my face with clean wet sponge
Both options are very effective. I use it twice a day (in the morning I use a soft facial cleanser, and in the evening more effective cleanser and then my sponge).
I like its exfoliating effect very much. My face is soft and smooth after using this sponge. 
With facial cleanser, I didn't foam it well
The sponge must be replaced every 2-3 months. As soon as your sponge gets harder and scratches your skin, be sure to replace it.

I will continue buying these sponges. And of course I recommend this to everybody.
