Crocheted from a 100% nylon yarn that is durable, but does not scratch surfaces. Each scrubber measures approximately 5" in diameter. Handy in the kitchen when cleaning potatoes and removing silks from corn on the cob. Great for cleaning many surfaces, including the tub and shower. They are washable, but should not be put in the dryer. My preferred method of washing them is in the top rack of the dishwasher--works great! I have attempted to catch the colors as accurately as possible; however, there may be slight differences between the color of the pictures and the actual items due to lighting, monitor, and other settings. This is a set of 3 single layer flat round scrubbers in dark green. Hand-crocheted with 2 strands of nylon yarn for thickness, for dishes, pots, or cleaning anywhere in your home.
