Abstract
An enhanced multipurpose twist tie is formed with two helically disposed wires encased in a sheath having a polygon shaped cross section, a longitudinal ridges, and detachable end caps. The wires are defined by a longitudinal length and a pair of wire termini. The wires intertwine in a helical configuration along the length of the sheath. The helical configuration compresses the wires together and also allows for a greater concentration of wire to be fit into the sheath. The sheath is defined by an outer face having a plurality of longitudinal ridges that extend along the length of the sheath to provide a grip for facilitated twisting and tying of the twist tie. An inner face has a polygon shaped cross section that restricts longitudinal and rotational slippage by the wires. The end caps detachably attach at sheath termini to form a smooth surface over wire termini.
