Lenovo Chromebook Duet Gen9 11M889 MediaTek 10.95 inch 83HH000UJP 4GB / Luna Grey Purchased on September 7th at K's Denki in Kanagawa Prefecture. I'm selling it because it was a little different from what I imagined when I tried to use it. The pen has never been used. I have disposed of the box. I will pack it carefully and ship it.
