I wouldn't ever consider going anywhere else. Bottom line (read on for detail) you get what you pay for. At SIX16 you get professionals and high quality piercing and jewelry from people that give a shit.
The staff is very chill, nice and helpful. Nick worked with me get the placement of my piercings just right. The pride in his craft is so evident. And the selection of jewelry is really unique and cool. Not your average stuff.
