Pocket calculators can sometimes be so small that you can't read the display or push the keys. Not this one! With a large easy to read 12-digit display, the Q-Connect Silver Large 12-Digit Pocket Calculator is the perfect pocket size for easy use, and its rubber keys make inputting even more simple. Supplied in a wallet to keep it free from scratches and marks, the calculator is powered by both battery and solar and has an eco-saving standby function.
