Sealed Tupperware Box

A transparent plastic Tupperware box with a tight-sealing lid, roughly rectangular and about the size of a shoebox. The box sits on a workbench in the control centre, its lid secured to prevent contamination. Doctors and technicians use it to isolate biological and radiological samples during examination, keeping the contents visible yet controlled. Watson orders the Hand to be secured inside this box after retrieval, ensuring it can't absorb additional radiation or influence the environment.
