Casio's solar calculator: lightweight with great features.
This is one of Casio's better ideas. the faux leather case encloses the sensor picking up light, and thus protects its electronics. The constant capability allows its use for slower financial calculations, and also for advanced checks on prime numbers.

The one I received from this supplier is in mint condition-that is better than new!
