This gaming die is balanced in the sense that the raised bumps on each face of the die are designed to be of equal volumes (and therefore equal weights).
This is the one inch (2.54 cm) version of the die with rounded outside edges. 640 mil (1.63 cm) and 820 mil (2.08 cm) versions of this die also available in the store. The model has been uploaded with color but is only offered in single color materials. You would need to color the part yourself with fine point markers or paint if you wish to have additional contrast on the faces of the die.
