The Hewlett-Packard HP 30b Business Professional calculator in its package

The HP 30b Business Professional is delivered with a very nice pouch.

This Hewlett-Packard HP 30b Business Professional was manufactured in April 2010 by a contract manufacturer in China.

The printed circuit board (PCB) of the HP 30b hides the single-chip calculator circuit under a black epoxy blob.
