Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: X Series, belonging to category: Calculator Devices

### Response:
The X-series includes a handy solar calculator (X-Mark I), a calculator with a printing feature (X-Mark I Print), and a practical wireless laser mouse with integrated keypad, display and calculator (X-Mark I Mouse). Characteristic for these multifunctional devices are their ecologically friendly materials. All three are made from residual material accrued from the manufacture of Canon technological products. The LCD display of the solar calculator, for instance, is made from optical parts of a digital camera, while the printing calculator consists of recycled material from Canon copying machines. The wireless mouse carries on the “green” concept and stands out due to its wide field of applications. All devices feature a straightforward, user-friendly design, and their glossy surfaces lend an air of freshness to sometimes dreary day-to-day work.
