Sci-fi hard-shell helmet for children, not primarily available in adult sizes; components need to be joined with glue.

The helmet top and the main body can be connected with M3X12 self-tapping screws (Note: The two screws at the rear of the helmet top are relatively hard to tighten and can be omitted).

Opening dimensions: 15 cm in width, 18 cm in length.
