Package Quantity: You will receive 8 fluorescent sticky balls Product Features: Upon receiving the decompression balls, please note that since the products have been enclosed during transportation and not exposed to light, it is recommended to place the sticky balls under sunlight or UV light for a period of time. Once charged with light, the balls will glow in the dark, providing entertainment and visual appeal Product Size: Each ball measures approximately 1.8 inches (4.5 cm) in diameter, designed to fit comfortably in hand for grip and stress relief. Not suitable for children under 3 years due to small parts; adult supervision is required during use by children. Encourages interactive play between parents and children Soft Material: Made from high-quality thermoplastic rubber, the balls are soft, safe, and durable. The surface is easy to clean; if dust accumulates, it may reduce stickiness temporarily. If the ball becomes dirty or loses surface tack, rinse gently with clean water and allow to dry—stickiness will be restored How to Play: These sticky balls can be thrown onto clean, smooth, and flat surfaces such as walls, ceilings, tiles, or desktops. They will adhere briefly before slowly sliding down, creating a fun and relaxing activity. Ensure the balls are clean before use to avoid any potential residue on surfaces.
