Stackable display.

Display stand for figures, ornaments, Pokéballs, or other display items. 
The display stand is infinitely stackable, each level can rotate relative to the previous level, and up to 8 arms can be added per display level.

Note:

If you're using heavy objects on the first level, it's advisable to use the arms with supports to avoid unbalancing the display. Caution: 

The joints are very precise and require some force to fit, making them difficult to remove (the arms, however, move easily). This is to ensure stability. If you plan to rotate the levels frequently, file the joint lightly before inserting it.
