ear cushion for Razer Tiamat 7.1 v2

Does anybody know where I can get a razer tiamat 7.1 v2 ear cushion replacement? I've contacted razer support recently to enquire about the replacement but they do not have a replacement in their inventory. The leathers are falling apart and it's deteriorating can anyone suggest where I can get a fit replacement? I've order some online before but the size does not fit my headset.
