Studios brings the best in tattoos, body piercing, and original artwork to the South Jersey area, showcasing their artwork not just through drawings, paintings, and sculptures, but also on the human body. 12 oz. Studios is a very creative and diverse group of individual artists that want to give something unique to each of their customers. When you walk into 12 oz. Studios, the first thing you may notice is all the artwork on the walls. You won't see tons of flash. There is a very small display of flash to be used for inspiration, and most of the flash in the rack is 12 oz. Studios artwork.
