Here are a couple of surface piercings on the nape of the neck. I always pierce these with 1.6mm PTFE plastic w/titanium balls to allow flexibility and initial comfort for the inevitable swelling. A few weeks after your pierced, maybe a month or so depending on your own healing process; return to the studio and I’ll trim/cut the plastic bar down flush. You can also change the heads or balls, though I recommend a 4/5mm ball minimum for the first few months.
