Replacement Blackwidow chroma V2 wrist rest

Hi The wrist rest on my Blackwidow chroma V2 has totally ripped and looks awful but the keyboard itself works perfect and I still love it. Is there any aftermarket place I can purchase a replacement wrist rest. Preferably an exact replacement, which attaches with magnets. If an exact replacement is not available and is aftermarket i would prefer a cotton covered one instead of the cheap plether on the original.
