About GRITSTONE Core Experience: As a spinner friendly to beginners, GRITSTONE offers high cost - effectiveness and can adapt to different hand shapes, making it easy for novices to get started. The pushing feeling, rebound, and sound are crisp, and the hand - feeling has a clear hierarchy. It can be carried around daily without fear of bumps, is durable, and is not picky about the environment. Design and Craftsmanship: It imitates nature and emphasizes details. Inspired by outdoor stones, its rounded shape brings a natural grip and a sense of security. The metal - making process is highly difficult. There are no flat surfaces, only full - curved transitions, and the yield rate requirement is strict. Matched with C - M - F design, the stepped concave patterns are like water droplet ripples, which are both durable and trendy. Detail Parameters: It has high compatibility. The diameter of the locking mechanism is 24mm, which is compatible with most locking mechanisms within 25mm. It supports the installation of 3 6mm beads. By default, it does not come with beads at the factory, and you can match them by yourself.
