The image shows a display case with a pink cloth on top of it. On the cloth, there are several small rocks and stones scattered around. The rocks are of different sizes and shapes, with some being black and others being beige. There is also a small white label on the bottom right corner of the image that reads "GACH, THAN - Tu chinh trắng hoi hoi đồng viet nững nật nᅭt mới mặt trong của bội học bảp" which translates to "Bricks, Charcoal used by Hoa Lo prisoners to write on the cement floor during lessons". The background is blurred, but it appears to be a museum or exhibition space.
