Take a sheet of A4 paper and fold it in half. Insert it with a short part in the upper stub of the magnet in the middle. Locate the two front screwdrivers and insert them between the sheet and the blank filler at a distance of 1 cm. from the edge of the sheet. Gently lift both the screwdrivers up. The upper edge of the filler will come out of the slot and the blank filler can be reached with the hands.
