To provide a clay composition capable of forming fine shapes, slender shapes and ultrathin shapes without using reinforcement, repetitively reusable, considered human fingertips liable to absorb toxic substances, safe and harmless.

The composition is obtained by mixing beeswax and pine resin at almost the same weight ratio and, if required, can be compounded with paraffin, stearic acid, talc powder and the like. A thin layer film-like form having 0.05 mm thickness and high elongation and strength can be formed. The composition is excellent in elongation and strength and can be formed into film-like products. The composition is softened at human average body temperature and hardened at room temperature, can be repetitively reused many times, uses natural crude materials and is safe to human bodies.
