Weird synchronicity. I passed that place earlier today (probably about the time you posted!), having never noticed it before and was trying and failing to figure out what the name was from the very ornate lettering. I got "something fox" before I whizzed past.
Looked like a great spot!
I used cream from horikitsune tattoo for shading on my back, crazy stuff, good for 2 hours.
Lots of tattooists I know use the same stuff, heard something about his dad being an anaesthetist idk.
He has a shop on Copenhagen street, or you can order it here.
