Today alone I asked myself twice, "How did my mom ever live without this?" I cleaned pen and pencil scribbles and drawings off the walls and permanent sharpie marker off the newly painted toy box. And nothing rubbed off except for what was supposed to. And the paint in our house is not great - when I lysoled the light switches here for the first time, it ran down the wall and ate the paint away in some places! Oops. Anyway, I go through these Mr. Clean Magic Erasers like crazy and LOVE them. How DID my mom live without them? What modern-day product do you wonder the same thing about?
