Met Life Snoopy Solar Calculator (With Battery Backup)

This calculator is twice as environmentally friendly than the average calculator. First, it is powered by the sun, although it does have a cell button battery (included) as a backup for those who live in Alaska or spend time in darkrooms. Second, the calculator is made from environmentally friendly “BioGreen” plastic which will biodegrade in a regular landfill within 18-60 months NEW (New Cell Battery Included)
