This light meter is in EXCELLENT physical condition but it is UNTESETD and I was unable to get the needle to move by exposing it to light!! The leather case is solid with moderate wear!! Approx. 2 3/8" X 1 5/8" X 1 3/8" in the case, and the meter is 1 7/8" X 1.5" X 1" thick!! Please see my many other camera and craft/hobby listings and email me with any questions!!
