The document describes a paper cube created from normal drawing paper. The paper is soft, flexible, and thin, making it weak on its own. However, by cutting the paper into strips and joining three strips to form strong equilateral triangles, then combining the triangles into a cube shape, the normally weak paper takes on new characteristics. Specifically, the thin paper becomes elastic and strong through the bonding of the triangles. The cube is named Trigo-Crown due to its crown-like shape formed by the equilateral triangles.
