This case fits the 10B, 10C, 11C, 12C, 15C and 16C series of calculators, those of the Voyager series of HP calculators.
This is a standard HP replacement case for the HP 12C Calculator. It is a vinyl replacement slipcase that HP provides for the 12C series calculator. It is thin and adds almost no extra size to the calculator, but protects well the financial tool you carry with you daily. Best for those that carry their calculator in the pocket or hand, and keeps it lint and dirt free. It shipped with all 12C calculators except the Anniversary.
