This is the leather case that ships with the HP 17BII+ Calculator. This case also fits the 11C, as well as the entire Voyager series of calculators including the 12C.
For those that like a little more protection for the 12C than the thin slip case that ships with the 11C and 12C calculators, and yet don't want the bulky 12C Platinum Anniversary case, this is the best case around.
