These are the most versatile sponge’s I’ve ever tried. They are flat, square and a bit stiff. But when you add a little water suddenly the stiff squares turn to velvet. They get a little thicker but not any bigger. Giving these cloths, one good squeeze good squeeze - eliminates all the excess liquid. They dry quickly keeping them anti-bacterial. There are so many things in your home that are “1 use”. Paper napkins, Paper towels, Disposable Dish Towels, Q-tips, Cotton Balls & Squares, Reusable Toilet Wipes, Hand Towels, Hair Towels, Fingertip Towels, Bread Basket Liner, and so much more. All of these items and more can turned into recyclable products. And it all started with this amazing sponge, that does the duty of multiple items in your house hold saving you hundreds a year. This “all in one” square, reusable cloth has answered the question a “What would I do Without This”?
