The Dragonballs!

Pro: Original Anime appearance, the 1-star Dragon Ball are all available to the 7-star Dragon Ball.

Pro: They never turn into stone balls

Pro: They come in a high quality box with cloth over the deposit, which they can be stored neatly and presentative

Negative: You can not summon Shenlong with these Dragonballs, and get thus fulfilled every wish.
(Are halt only visually Dragonballs without magical effects)

Pro: If you use them too often, no evil dragon can arrive, as in GT

The Dragon Balls themselves:
Just like in the series they are small enough to be placed in the mouth can, this should be avoided due to risk of suffocation (Piccolo could swallow it, but Goku is it almost choked, hence no one should try to swallow or Saiyan a)

The build quality is convincing, and all the Dragonballs have the stars properly disposed of according to series.
The balls have no external interfaces.
However, one can see the interface, if one considers the level at which the stars are placed on the page, otherwise this is not apparent, however, since the balls were elaborated.

The balls are massive, and should be stored in the supplied box ideally.
The supplied box has a slight magnetic closure, and the storage of the individual Dragonballs consists of a styrofoam plate with storage wells for the Dragonballs, the a loose-orange cloth is attached (moored / stapled to the sides) that they Dragonballs gently overlaid.
