The Mahavir Premium 4D Ring Binder File (for 4-hole punched sheets) is ideal for filing documents and other important papers, for a maximum size of A4 (29.7cm x 21.0cm) (11.7inch x 8.25inch). The clip size is 1.5 inch (40mm) that allows for filing of 350-375 sheets (80gsm) or 375-400 sheets (70gsm) comfortably. Only 4-hole punched sheets can be filed. 
The ‘D’ shaped nickel plated clip allows for easy filing and less strain on the punched holes. Nickel plating allows for long life of the clip and significantly reduces the clip’s tendency to rust. The clip comes with a gripper with a locking mechanism that presses the pages downwards and holds them together. 
The Cover Material is made from dual shade vinyl coated paper which gives the file a long archival life. The cover is light weight paper board.
