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 toyit needs to be wound with multiple turns of the included string to achieve stable rotation at sufficient speed. If only a few turns are used, the rotation will be slow and unstable.Nice Toy to Pass the Time: The gyroscope has a simple yet elegant design and demonstrates the fascinating physics of defying gravity, making it engaging for adults. It's not only fun to play with but also a great way to pass time during idle moments.Quality and Durable: The finger gyroscope is made from high-quality materials, strong and reliable, resistant to rust and corrosion, not easily deformed or broken. The smooth surface ensures comfortable handling and long-term use.Wonderful Present: This metal spinning toy is delicate and intriguing, making it a great gift choice for birthdays or special occasions. Suitable for friends, family, colleagues, or anyone interested in physics and science, it encourages learning and exploration of scientific principles.Note: A small bottle of lubricant is included. Before first use, apply the provided lubricant to both ends of the gyroscope to ensure smooth operation.Size: Product size approximately 70 x 92mm, base approximately 38 x 32mm Material: Zinc alloy Color: Gold Package Contents: 1 x Gyroscope 1 x Drawstring Only the above package contents are included; other items are not part of the package.
