New, true leather case for HP Voyager calculators, including HP12c, HP12c Platinum, HP10c, HP11c, HP15c, HP16c calculators.

Note: this is not an original HP product.

The original Voyager calculators had a vinyl case that resisted quite well the passage of time - and that was designed to be kept in the jacket pocket. It also had the knitting "inwards so that it occupied the less possible space for a given volume.

Later versions (including anniversary units) have been made in false leather (called PE), which has a very low resistence to external scratches. There are several types but all of them in my possession have now a very bad aspect. For the current HP12c Platinum, the case is not even suited for jacket pocket, since it has very square corners

We have decided to create real leather cases that stand the passage of time, made with the same material that pocked cardholders and money holders are made. We have selected a manufacturer in Ubrique (Spain), famous for this kind of work. We sent to them the originals and the calculators that go with it, so that the case you have with you is not something similar that fits well - it has been expressly designed for your calculator

Please take a look also to the leather cases for Pioneer (HP17bII and HP42s types) and HP41c cases.

Later versions (HP17bII+) have been made in false leather (called PE), which has a very low resistence to external scratches. There are several types but all of them in my possession have now a very bad aspect after few years. For the current HP17bII+, the case is not even suited for jacket pocket, since it has very square corners.
