You are purchasing a set of four different nylon netting scrubbers one of each a flat scrubbie, a half moon, a round double ball, and a dish cloth back scrubbie I used sugar and cream yarn on the back of the scrubbie. This will let you try all four of my scrubbies and then you will know which one you like the best. These scrubbers are great they don't scratch can be used on almost anything: showers, shower doors, stove tops, counter tops, sinks, dishes, Teflon pans, head lights on your car to remove bugs for just a few. Any questions please send me a message.
