Power turned on, but one has horizontal lines, and the other has a sticky back. I initialized them just in case, but detailed operation has not been confirmed. There may be other defects as well, so I'm selling them as junk. These are old, used items, so please understand that the condition is as-is. Please consider them for parts or other uses. Please refrain from purchasing if you are sensitive to condition. They will be sent via Nekopos with simple packaging. Condition: Junk, as-is
