Abstract
A device made of a thermoplastic material having two portions connected together with a web or hinge. A first portion forms a main body and the second portion forms a lid or cover. When the lid is aligned and closed onto the main body, the shape of the unitary device may be spherical, elliptical or another shape. The main body allows for one or more lines or strings to rest within a channel formed in the main body parallel to a pivot axis of the hinge so that when the lid is closed into the main body the strings are trapped within the channel of the main body by the lid.
