[Responsive Yoyo for Beginners] MAGICYOYO K2 PLUS is one of the top recommended functional entry-level yo-yos. It is an excellent kids' yoyo, ideal for beginners to practice basic string tricks including 1A, 3A, and 5A. With just a gentle tug on the string, it returns to your hand easily. [Dual Purpose Yoyo – Also Pro Unresponsive Yoyo] The K2 yo-yo is responsive out of the box with a slim bearing. An unresponsive KK bearing is included in the package. When you advance to the next level, simply replace the bearing with the included KK bearing to convert it into an unresponsive yo-yo. No need to purchase another yo-yo—great value and versatility. [Premium Quality] Made of high-quality PC material, this yo-yo features a beautiful crystal color, is wear-resistant, pollution-free, and safe for children. Durable and sturdy construction makes it a perfect gift for kids, friends, beginners, and family—ideal for Christmas or birthday gifts. [Important Information] 1. For responsive yo-yo mode, if the yo-yo does not return sensitively, it is recommended to apply a small amount of lubricating or rust-proof oil inside and outside the bearing. 2. After converting to unresponsive mode, the yo-yo will not return to your hand when pulled. You will need to learn a trick called a bind to bring it back.
