Where to purchase Blackwidow Chroma V2 wrist rest

The Razer store does not have any option for replacement wrist rest for the Blackwidow Chroma V2 keyboard (larger than full size with macro keys).

I have two Blackwidow Chroma V2 keyboards, both several years old but fully functional, however both wrist rests are wearing out and peeling on the left side.

My wife tried to purchase the fits all full size keyboards wrist rest and it is not only too short but it does not align with these keyboards to be functional replacment.
