Yes! Here's how it will work:
You must choose a reward base model: 2-pc, 5-pc, or 8-pc.
The 2-pc is a standard two pieces.
The 5-pc starts with the same two pieces and you can choose 3 additional pieces in the same trim (Gold, Rhodium, Stainless).
You can select and pay for additional pieces in any trim during the BackerKit survey at the conclusion of the project.
The 8-pc already has every piece, so there is no customization there; all eight pieces are the same trim.
ADDITIONALLY, you will have the option to upgrade to a Gold or Sterling necklace to replace the black cord on the Stainless trim models. That is also during the BackerKit survey at the conclusion of the project.
