Brand New Authentic — buy with confidence
RUYI S is a dense-track mechanical slider upgraded for smoother travel, clearer sound variation, and a more rugged everyday finish.
The redesigned track uses a denser layout with fewer segmented grooves, creating more distinct pitch changes and smoother movement from start to finish.
The surface combines DLC treatment with stonewashing and aging, giving RUYI S a darker, worn-in industrial look with improved resistance to everyday scratches.
The engraved slogan reads:
“Stop Self-Depletion, Fear Nothing.”
The stainless-steel body is finished with 220-mesh sandblasting followed by approximately 5 hours of pearlescent stonewashing.
The result is a smooth, warm-touch surface with a less abrasive feel and a durable finish suited for regular carry and play.
