Silk is the most ideal cloth to clean fine optical lenses, camera lenses, CDís, eyewear, and all those little screens on cell phones and other digital devices. This is because pure silk is by far the softest natural fabric and it will not leave hairline scratches on sensitive surface materials. Silk Wipes by Royal Silk come in a set of three colors, and each is about 8" square. Washable. Imported. You will not find these utilitarian silks anywhere else.
The colors of the three silk squares are assorted and not always as shown in the picture.
