This is a massive calculator which I purchased overseas and have owned for a number of years. Very minor use and mainly just for display purposes. There may be minor scuffs, but it powers on and the buttons work perfectly.

Couple things you may not be able to tell from the photos:
The buttons are soft rubber. 
Solar charging panel is pushed a bit "in" at an angle, but I have not bothered to open it up to investigate further. 

Choose Fedex or USPS.
