Thank you for viewing! This is a rare Black Shark fidget toy! It has been opened once for inspection and quality check. This is a high-end model that fidget toy enthusiasts will love to use! Its features include three types of gimmicks. The front has a mechanical slide and 360-degree rotation. The disc on the back makes a "gyuun" sound and vibration like a shark's roar, which is very pleasant and addictive. It feels similar to the MOT Groove Slider. It fits comfortably in your hand, about as well as the Ghost fidget toy I have listed separately. Weight is approximately 100g. Please understand that the item has been taken out of the bag once for inspection.
