The Star version of the Atom has less similarities with the Super Hero than its Candy Firm counterpart, other than the fact it has a single dome. It is made from the same material as the Hero Suoer Star disc. That makes it light weight, but also very biteproof, grippy and flexible (also in cold weather).
Super Atoms have a comfortable grip and are especially good for cold weather play. Easy to throw for all skill levels and micro dog-friendly.
Next to the Star version of the Atom, there are also Candy Firm and Candy Soft versions available.
