My new Razer Kishi has something scribbled on the back

Hi, I ordered a new Razer Kishi from amazon.de here, sold directly by Amazon EU S.a.r.L.: https://www.amazon.de/-/nl/gp/product/B084W8P5FP/ Note that it I bought it marked as new. Not refurbished, not used. It got delivered a few days ago. The packaging looked like it was unopened, it works, everything is fine. But my Kishi comes with some scribbling on the back, made by a marker. At first I neglected it, thinking it was a detail of the back plate. Upon closer inspection, I realized it is clearly made by a marker, and I can find no promotional material that shows anything other than the logo on the back plate. Is this normal? Do other people's Kishis also come with this? Or have I been tricked in buying a used or refurbished Kishi that was carefully repackaged to look as new? I don't care about how it looks, but I will not stand for buying a product that is sensitive to wear and tear, specifically as new, and getting something different in its place. Therefore I'm hoping people can confirm this is normal, so I can give it a rest.
