PLEASE NOTE: All MIDNIGHTFACTORY AUTRIUM gold pieces are made to order and require 7–14 working days to craft. For this product, each piece carries a unique serial number starting with 26 (for Year 2026), produced only once.

When a serial is sold, it is never made again. A limited yearly edition — your piece is the only one of its kind in the world.
