The once edgy stones endure a long journey down the river to the ocean shore. Along the way, the edges are curved into irregular shapes. Feel the eternal journey of nature as you continue to use these pebble-shaped erasers.

After continuous usage, it becomes rounder like the pebbles along the shore.
