The ROKR Gravity Swing series is inspired by the principle of center of gravity balance and consists of three main parts: a base, a frame, and a swinging component. Unlike other ROKR series, this one features colorful parts and playful designs, making the gravity-powered movement look especially charming and eye-catching. For example, when the Ocean Fisher swings, it vividly recreates the scene of a fisherman braving the waves. Place them on your desk to enjoy their adorable swinging motion anytime.
