This is my first box of Efke, and in the dark I couldn't find the notches as I held the brick of film in one hand and felt back and forth with my fingers. The 50 pack of 4x5 Efke BW asa25 I had was in three boxes then a thick plastic bag then cardboard top and bottom, and thin tissue seperators between each sheet--sometimes more than one slip of tissue paper. The notches are rounded and VERY shallow. Not until I lifted the first sheet of film (with a large thumbprint dead center now) was I able to find the "notch." Worth burning a sheet just to see it in the light.

I havent seen anyone else mention this so having experience loading only kodak, I wanted to put in a heads up about loading Efke film. Sometimes the notch is noticeable only after lifting the sheet of film. They are there, but very shallow yet obvious when holding a single sheet.
