It is a soft exfoliating sponge.

Before, scrubbing hard with an exfoliating towel was exhausting and left my skin red, but lately, using this sponge requires much less effort, and the dead skin just falls off easily, making it so convenient. Best of all, since it removes dead skin without irritating the skin, even the kids use it without fear. My skin used to turn white and look unsightly if I didn't scrub for just a week, but using this sponge is so much better. If you think it's too big, you can cut it in half like this to use it.
