Canon LS-12TU II calculator with a compact design and tax calculation function. I bought this in an emergency at a convenience store because I forgot my calculator on the day of the exam. I only used it for one day, the day of the exam. It works without any problems. It's a very portable size, approximately 125mm tall x 80mm wide x 18mm thick. - Model Name: LS-12TU II - Brand: Canon - Color: Silver - Features: Tax calculation function - Size: Compact design Thank you for looking.
