Sistema Ring (4-hole, 9mm, PA)
The Sistema series is first family within Parts of Four. As a mode of creation it expresses the core principle of P/4 which is modularity. The "body" and "insert" are separate parts joined together with pins. This leaves endless possibilities for iteration of material and form combinations.
All sizes are US RING SIZE
RINGS are generally measured using the diameter, the easiest way to determine this is by measuring a ring you already own.
Please keep in mind the width of the ring you are ordering. The wider the ring is, the larger the size should be for it to fit as you would expect since it is harder to put on. For example, your size on a 4 mm and 17 mm rings would not be the same. The 4 mm would be your exact ring size if measured by a jeweler (or a ring measuring tool) and the 17 mm would probably be an entire size up, or at least a half size up. If you have any confusion about this it is better to allow us to help you figure it out.
We can offer ½ sizes on request.
