White calculator with tax calculation function, solar powered. - Brand: Canon - Model: SI-120T - Color: White - Power Source: Solar powered - Features: With tax calculation function - Key Arrangement: Standard key arrangement Height: 14cm Width: 9.5cm Thank you for viewing. I used it for about a year, but I haven't had a chance to use it since then, so I'm selling it. It's difficult to see in the photos, but there is some slight yellowing on the keys. It can be used without any problems as a calculator.
