Perfect Shaker, the brand behind the now well-known Hero Series of shakers, has confirmed the coming of yet another addition to its popular product family. When we first met the brand back at the Olympia it had two items in the Hero Series with Batman and Superman. Just over one month ago it then added Wonder Woman to the line, making it a total of three. Number four is now ready to go with Perfect Shaker currently hinting at it being unveiled at this weekend’s LA Fit Expo. Based on the other three we can only assume the fourth is going to be another DC hero, with our guess being Green Lantern.
