Sanding sponges are useful for sanding hard-to-reach areas and smoothing surfaces in between coats of paint. They're also great for removing finger marks. At Rich Tool Systems, we carry Fine, Super-Fine, and Ultra-Fine foam sanding sponges measuring 4.5" x 5.5". These sanding sponges are flexible and conform to all shapes, allowing you to use them wherever necessary. Fine is 320-400 grit, Super-Fine is 500-600 grit, and Ultra-Fine is 800-1,000 grit. Each comes in a pack of 25 and is manufactured by Sungold Abrasives. We at Rich Tool Systems are proud to carry everything you need for all stages of your project, from start to finish.
