I have absolutely no idea how to use these, not sure if they all work properly or not, this is a lot of 5 . May not operate correctly or maybe they work just fine, no idea.

This lot of 5 Bakugan toys includes a mix of characters such as Brawl, Brawler, and Blue, all from the Bakugan Battle Brawlers franchise. Manufactured in 2008 by Spin Master, these vintage action figures feature transforming abilities and come in a 1:8 scale. Made of plastic and metal, these original licensed reproduction toys are part of the animated adventures series and are based on the popular TV show Bakugan. Perfect for collectors or for repairing broken toys, this lot offers a variety of colorful and unique characters for fans of the cartoon and TV character theme.
