Ergonomic Wrist Rest Pro warranty?

Hey dear Razer community, I recently bought some Razer components and would like to register them. Unfortunately, I can not find the product number of the "Ergonomic Wrist Rest Pro" neither in nor outside the packaging. My question would now be: Does the "Ergonomic Wrist Rest Pro" no warranty? And if so, how do I register it without the product number?

Yours sincerely
