This is a ligament-free skeleton model made by 3B Scientific. It has casters (see photo 4). The height is approximately 160cm (measured by an amateur). The skull part originally doesn't fit perfectly, and there may be gaps depending on how it's assembled, but it can be made less noticeable by applying transparent tape (see photo 3). It's in good condition, but it has been stored at home, so please refrain from purchasing if you are concerned about minor details. Thank you.
