These are genuine Hori dust washers and shaft covers—something you almost never see sold.  

The shaft cover feels very similar to Sanwa Denshi, but the dust washer is where things get interesting: thinner, low-profile, and finished in a clean matte texture that gives your setup a unique look.

We’re including two dust washers (Hori only included one originally), and all units are brand new, pulled from a large joystick lot we secured years ago.

Once these are gone, they’re gone—Hori does not sell these parts individually, and we won’t be able to restock them.
