The ProMaster Premium Soft Cleaning Cloth removes dust, dirt, oil, fingerprints, and more from optical and delicate surfaces. Use it on lenses, filters, LCD screens, and viewfinders. This cloth works well dry, or it can be used with a high quality optical cleaning solution such as ProMaster OpticClean. A convenient cloth storage pouch is included with a fast, easy-open top. Just squeeze the top and it pops open! The pouch slides into a camera bag or pocket and it also has a fabric loop for attachment to a lanyard or carabiner.
