Tartarus V2 Wrist Rest disintegrating

Hi, I had purchased the V2 in 2018-19 to aid in my photo editing workflow. Unfortunately, due to Covid, I had not used or touched it for a very long while. I had recently taken it out of the box, but the wrist rest had completely flaked out. Had tried finding for the replacement part of Razer's main store to no avail, and my warranty on this device is not available anymore. I am looking to replace just the wrist rest and not the main device as it is working fine. Thanks.
