Indeed the regionally confused label was a dead give away. I have another bootleg arriving with a similar error. Though I suspect it will be the same type of hardware as this one. The shell design was really close to official. And the markings on the backside were really close...if only they didn't blow it with the label.
I did a rom dump it was indeed the Europe rom the cart contained. So at least 90% of the label did correspond to the version of the game the label indicated it was.
This cart boots on my 2DS XL by the way. Assuming the rom is 1 to 1 to the Europe release it probably passes DS Cart white list checks too and will boot on non CFW'd consoles...Though I currently do not have any to test that on.
EDIT: Here's a photo of the backside. If it weren't for the label you'd have to look pretty closely to tell it was a fake.
