NOT AFRAID TO... OPEN UP.
This ring appears to be a button that is fastened through it's hole. In fact, the button and hole are made from one continuous piece of stainless steel that is made using 3D printing technology. The ring is adjustable because the "button" end is not attached to the "hole", but passes clear through. This allows the ring to be slightly adjustable.
Some of the pictures show the button "sewn on" with thread. The thread doesn't actually hold the button on, it's purely decorative. You will receive one ring in the sizes and finish of your choice (see below) and a free sewing kit which includes everything you'll need to sew your button on many times to match your outfit or mood.
This ring was is made of 3D printed stainless steel that is infused with bronze for strength. It can also be plated with antique bronze or 24K gold. For more about our production processes, visit our production page
