A pencil eraser starts in a firm, even condition. Its rectangular shape sits squarely on the pencil's end. When pressed against paper, it lifts pencil marks smoothly, with only faint traces left behind.
The first signs of change emerge after repeated contact with paper. The sharp corners begin to round off gently. The rubbing surface develops subtle scuffs, visible upon close inspection. Erasing continues effectively, though small particles accumulate nearby.
With ongoing use, these alterations advance. The eraser shortens measurably along its length. The texture turns coarser, shedding more noticeable flakes during removal of marks. Firmer pressure is now part of the process, and residue builds up more readily.
Progressed Condition
Later, the eraser appears markedly diminished. Its height is reduced significantly, making it softer to the touch. Marks lift less cleanly, often leaving faint smears. Precision in application decreases as the shape becomes irregular.
This state reflects the eraser's transformation through successive stages of wear, observed over time.
