About Shadow Raider Mechanical Ring II: Shadow Raider showcases a unique mecha style. The ultra - thin Teflon bearing, processed with precision, not only has clear edges that are not hand - cutting but also makes the ring more comfortable to wear and easy to carry. Moreover, it integrates the dual - hand - feel modes of the snap - ring and the squeak - ring, offering a rich and diverse playing experience. How To Play Hand - feel Experience: Switch between the two hand - feel modes of the snap - ring and the squeak - ring to enjoy different decompression feelings. Fun DIY: It is possible to install 12 light-emitting tubes of 1.5x6mm without glue, and enjoy the cool effect of the light-emitting tubes when rotating. (The light-emitting tubes need to be purchased separately.)
