ACEdc Thunder Fidget Spinner

About the Thunder

Thunder by the internal and external two bearings (R188 & 6703) to form a linkage, the internal rotor putting magnets or Buck ball without glue, and then with the main body of the large magnets (install without glue) to form the linkage of attraction/repulsion.
The linkage structure enables the rotation to drive each other when it is not synchronized, and it emits a thunderous sound, creating a strong sense of vibration in the hand.
The external shells are fixed by screws and can install four 2x 12mm and four 1.5x6mm tritium tubes to achieve front and side light shadow effects.
