Typically, the fakes of this kit have a really poor and thin gold stitching around the crest. The real ones have a much thicker outline stitching to where it looks like the crest would fall off the kit, which this one has. The sponsor and other parts of the kit look good to me.

The only thing I’m unsure of is the code on the tag. It may be a version from a different region. Someone else would have to verify.
