This 1.2mm, 16g septum piece is handcasted in recycled sterling silver by Uppsala finguteri after I model made by me. When I receive the piece from them I smooth the edges and give it a brushed, slightly distressed finish.
These measurments are inner mearsurments: Length: 12mm Width (at the widest point): 9mm Opening:7mm
This is a twist open ring, I've been making a little video showing how to open and close these rings. Check it out under my guides in the menu
