Judging by the product photos, the 6.5" and 8" versions have different designs depending on the material used, the two legs and how the legs are fixed. Made of metal and very well fixed by the handle. Despite the fact that I only have one leg, this is a study, although the figure is heavy. I bought two 8" versions and am very happy with them! Avoid the 6.5-inch version if you can.
