This is a Casio solar calculator, the DF-120GT, with a 2-WAY power supply. No batteries are required. I bought this as a spare for home use, but I haven't had a chance to use it, so I'm putting it up for sale. It's new, but it has been handled by a person, so please refrain from purchasing if you are sensitive to this. Due to shipping costs, I will remove it from its case for packaging and shipping. Please refrain from price negotiations. Size: Length 17.5cm, Width 12cm, Thickness 2cm, Weight 192g Calculator Casio Calculator Bookkeeping Tax Finance Commerce Type: Calculator
