I thought I was getting SIX (my fault) but $12 for ONE is outrageous!
Crate & Barrell used to sell small red sponges surrounded by a scratchy nylon material and they were just WONDERFUL!  I have bought so many things from Amazon and elsewhere trying to find something equivalent.  Well, wishful thinking must have overcome my ability to read and take in accurate info.  I actually thought I was buying six scratchy things with a thin sponge inside and thought the price for six was reasonable.  So, so wrong!  And it is much bigger than I had anticipated.  For what I wanted, it would be zero stars, but it seems reasonably well made, so I settled on two stars.  If I have more to say after a period of use, I'll add to this review.
Rating: 2 stars
