发明名称 Layered eraser
摘要 A layered eraser, comprising: a plurality of eraser layers, comprising at least an innermost eraser layer and an outermost eraser layer; the outermost eraser layer containing the innermost eraser layer; each eraser layer adjacent at least one other eraser layer; each of the eraser layers having an outermost surface. The layered eraser may be adapted to fit about a writing instrument. Each eraser layer adjacent another eraser layer may have different shaped outermost surfaces. Embodiments include different eraser layers in the shapes of simulated space ships, simulated dinosaur heads, and simulated planets. In a preferred embodiment, the plurality of eraser layers comprise an innermost eraser layer, at least one intermediate eraser layer completely surrounding the innermost eraser layer, and an outermost eraser layer completely surrounding the at least one intermediate layer, one or more eraser layers being exposed after at least a portion of the layered eraser is worn away.
