This is only the little plastic insert, which is epoxy + chrome paint + red xf paint. They are not printed, and take actual effort to make (I got a whole cup of failed ones!). The close up is on both the advert and this post. I can give you more pictures but they'll all look kinda the same.
I understand that its pricey, but if I was a chinese company that could make them in the hundreds with ease, it would've been much cheaper.

> Do you just use a screwdriver while the emblem is on the car to pop the cover up and replace this or does the decal have to come off the car for the insert to be replaced?
A thin blade might help to pop it out, the glue itself is probably deteriorated already (usually visible by more orange-yellow spots in the red due to water soaking into the tape behind it). Usually its already gone and you only need to clean up the glue residue.
