An external hard disc, the G Series, minimizes environmental pollution through the use of environment-friendly plastic. Patterns have been effectively used for the surface, removing the need for a painting process. In compliance with the RoHS Directive (Restriction of (the use of certain) hazardous substances), halogen-free plastic was applied to the product, which has been decorated with small patterns that change with light. These patterns create images of nature, such as african baobab leaves, thereby emphasizing the design concept of considering the environment and applying environment-friendly material.
