So I found a coupon in the box that the erasers came in and just had to use it! It was for Mr. Clean Eraser for the Bathroom. This sponge is thinner and shaped a little differently. It also has a cleaner in it. Although it didn't work as well as the original eraser, I still liked it. I also liked the smell of the cleaner they used. It was not overpowering. I would diffently recommend this product. Go get one and try it. Your tub will thank you.
