Where is the serial number on an Extreme Pro USB 3.1 128 GB

I have 2 Extreme PRO USB 3.1 128 GB drives from Amazon Canada supplied by Electron SH Canada and fulfilled by Amazon and can not fine any evidence of a serial number.  The packaging seems legitimate and include to sticker for RescuePro Deluxe.  The supplier has good ratings on the site but no apparent separate Internet presence.  Is there a serial number?

Same problem here.
