Assortment. Styles may vary. Each sold separately. Chosen at random. Unlike other bearing style yoyos, the Magnetar bearing is affixed to the axle so that there are no parts to lose. This is a significant improvement that enhances player experience. This eliminates the need for rubber pads or spacers so that you won’t need to order replacement parts. Because it is modular, you can unscrew your Magnetar to lubricate axle or change the string.
