Micro-Claire® Micro Fiber is 100 times thinner than a human hair, yet incredibly durable. Micro Fiber displays thousands of "edges" on each thread due to its sheer density. The Micro Fibers are so small that they clean away grime that other fibers simply can’t detect. The tiny fibers clean microscopic dirt, providing a brilliant streak-free shine. Great for cleaning CD’s, camera lenses and screens too! - Washable and reusable.
