Abstract
A protective case for a mobile device is disclosed. The protective case includes a substantially rigid outer shell and an inner case softer than the outer shell. Both the outer shell and the inner case are made of a compostable and/or biodegradable material. The outer shell includes a first planar back surface, first flanges positioned at least two peripheral edges of the planar back surface for securing the outer shell to the inner case, and open corners for exposing raised corners of the inner case. The inner case includes a second planar back surface, and second flanges around a periphery of the second back surface for securing the inner case to the mobile device. The raised corners are configured to protrude through the open corners of the outer shell.
