A paper fastener comprising:

• a base including two ends each having a leg extended therefrom, the leg foldable relative to the base;
• a sheath for slidably engaging one of the legs, the sheath comprising an open bottom forming a cavity to receive the leg, wherein the sheath at least partially covers the leg and is operative to engage through sheet materials;
• the sheath comprising at least one guide tab extending from the open bottom and foldable therefrom, wherein the guide tab comprises a flange bent relative to the guide tab to form a recess between the flange and the guide tab, whereby the recess is configured to receive the leg;
• and
• wherein the guide tab is sized to fit through hole-punched sheet materials.

A paper fastening attachment for use with a fastener having a base including two ends each having a prong extending therefrom, the prong bendable relative to the base, comprising:

• a prong cover shaped to slideably engage and at least partially cover the prong, the prong cover comprising:
• a top end and an open bottom proximate the top end, the open bottom to receive the prong;
