Design: This gyroscope toy features a mechanical structure without lubricated bearings. When the gyroscope is rotating, the base may experience slight movement. Please note that patience is required when using this toy, as it needs to be wound with multiple rounds of string to achieve stable rotation at sufficient speed. Winding only a few rounds may result in slow and unstable spinning. Nice Toy to Pass the Time: The gyroscope is designed with a simple and elegant finish, demonstrating the force that defies gravity, which can fascinate adults. It is not only entertaining but also a great way to pass time during idle moments. Quality and Durable: The finger gyroscope is made of high-quality materials, strong and reliable, resistant to rust and corrosion, not prone to deformation or breakage. The smooth surface ensures comfortable handling and long-term use. Wonderful Present: This metal spinning toy is delicate and engaging, making it a suitable gift for birthdays or special occasions for friends, family, colleagues, or anyone interested in physics and science, helping them learn about the world and explore scientific principles. Note: A small bottle of lubricant is included. When using the product for the first time, apply the included lubricant to both ends of the gyroscope to ensure proper operation.
