Time to clean shop---I just don't use this item. CBL Color Balance Lens. Another WB tool---easy enough to use. Incredibly nice packaging. The Koreans are getting really really quite polished. Retails for $117 at B&H. http://www.bhphotovideo.com/c/produc...s.html#reviews
This one is like new. $50 includes shipping CONUS.
