Plus, it's satisfying to come home from work and feel like you really washed all the the crap from the day away. *Sigh*
The other lingering concern is whether it is actually any more sanitary than the nylon poufs. I can't find a description of what is made of anywhere although I assume it is man-made materials. ULTA.com claims that it is recyclable. If anyone knows, please leave a comment.
All in all, I'd say the Exfoliating Sponge is the best $4 I've spent in a long time. I just hope it's not all germ-y.
