Sell my iPad mini 4 bought last year

I am a master student at Stanford, and I want to sell an iPad mini 4 I bought last year (October, 2017) at Stanford bookstore:

Here is the information of my iPad:
Color: Silver
Storage: 128G
connectivity: WiFi

I seldom used it since I bought it and it's 90% new. No scratches on the screen or the back.

I bought it with the original price + tax: $439.91 and I'd like to sell it at $300 (we can discuss on the price)

I will also give a brand new protector case as an accessory as well.
