A folder of a type opened in presenting 8 {fraction (1/2 )} by 11 inch documents to a business associate or other interested party, in which a side and bottom edge of the documents are previously manually inserted into cooperating isosceles triangles along the side and bottom of the folder, the manual insertion being to the extent of wedging the thickness of the documents along the side and bottom edges into a gripping engagement with the progressively diminishing clearance between the converging sides of the isosceles triangles, to the end of maintaining a neat appearance in the folder both prior to and in the subsequent presentation of the documents.
