Made for us in France, Trader Joe's Pop-Up Sponges are truly handy helpers when it comes to getting rid of grease and grime. They're made from natural vegetable cellulose, which makes them compostable, but equally as intriguing is the way they are packaged. The dried cellulose is squished down so we can fit 12 Sponges in each package! When you're ready to use, soak one in water and watch it pop up before your very eyes into a Sponge about 4 inches wide, three inches long, and an inch high! Sturdy enough for tough cleaning jobs, these Sponges remain gentle on your dishes & cookware.
