D2 pad 7" tablet 4GB memory as is for parts cannot test if work white or black

This is a D2 PAD with WiFi 7" Touchscreen Tablet PC. Runs on Android 4.1 (Jelly Bean) Operating System. This has a plastic screen saver over the screen which is intact; there are a few scratches on the back. I have no way to test if these are working so am selling them for parts only. I have two of these: one has a white back and one a black back. Both are in the same condition.
