These smart calculators are quite different. They are made from plastic and are both solar and battery powered so they can be used anywhere and they come supplied with a button cell battery so they are ready to use immediately. These calculators will be printed in digital full colour to cover the entire surface apart from the buttons and display windows so they will be totally unique and eye-catching. Your full colour print is set under a clear window so it will never fade or be rubbed away. Your large print area is 79mm x 117mm so your print will be highly visible on these useful calculators as they sit on desktops and tables everywhere. A calculator always makes a popular promotional gift and with no minimum order quantity, you can design a one off as a personal gift for a colleague, friend or family member.
