This is a standard konjac sponge. Very affordable and comes pre-soaked, which is great, as it saves time before the first use. The sponge provides gentle exfoliation, I use it with a face cleanser, as the konjac sponge helps it foam very well. After using I squeeze out the remains of water and hang it in the bathroom, I soak it a little bit before every use and microwave it in a bowl of water every week to kill the bacteria. Repurchase.
