Difference between these two "DeathStalker V2 Linear US" keyboard versions?

I’m about to buy DeathStalker V2 keyboard with Linear RED switches and US layout, but I found that there are two versions with two different model numbers, but I couldn’t even find even 1 single difference between them, so I want to ask if anyone knows if there is any kind of difference between them:

Razer.com’s version: “RZ03-04500200-R3U1”
Razer.com/eu-en/’s version: “RZ03-04500100-R3M1”
