Its basically 100% new but has missing case stands that keeps it from moving around on platforms.

    • Basic
Looks like the picture, BUT! It didnโ€™t come in a box or anything. It came in a small flimsy envelope that easily could have broken.

The media could not be loaded. I bought this calculator for my daughter and shipped it overseas ,but when she tried to use it the zero button didnโ€™t work . I am stuck now because return it will cost a lot of money . I donโ€™t know how you people ship something without inspection ?
