Double - layer Sliding Play: Hold the outer shell of the slider and push the inner liner to slide. Feel the Q - bounce hand - feel and the sound effect of the tuning fork, and enjoy the unique stress - relief experience brought by the double - layer sliding.
Bead Replacement Play: First, use the default zirconia beads to feel their Q - bounce play hand - feel. Then, replace them with POM beads and compare the differences in the tuning - fork effects of the two to find a stress - relief method that better suits your preferences.
The materials of the options are all for the outer shell, and the inner liner is made of stainless steel.
