AULDEY (officially called "Audi" in Japanese) is one of the world's leading toy manufacturers in China, and produces yo-yos as one of the many toys they produce. They produced the Chinese yo-yo animation "Blazing Teens" and released a yo-yo in collaboration with the show, which sparked its popularity and led to a huge boom in China. Utilizing the product development capabilities unique to a major toy manufacturer, many yo-yos are equipped with unique gimmicks, and the playfulness of their products is also one of their attractions. On the other hand, they have also been producing yo-yos for serious competitions since the late 2000s, and the name Audi has become known around the world for the development of inexpensive yet high-performance metal yo-yos and the performance of Chinese player Luo Yi Cheng, whom they sponsored at the time, in world championships. They are actively approaching the competitive scene, sponsoring not only Chinese championships but also Japanese, Asian, and world championships.
