Handmade Machine washable No scratch These are approximately 4 inches in diameter. I cut strips of nylon netting to crochet them. They work great for scrubbing pots and pans, stove tops, shower doors, vegetables (potatoes, carrots etc) and even getting bugs off the grille and windshield of your vehicle! All without scratching any surface. Throw them in the dishwasher or washing machine to get them clean, just don't use fabric softener or a dryer sheet in the dryer, and they will last longer.
