Material Crown, stylized as MATERIAL CROWN, is a high end Japanese brand, which manufactures and sells jewelry, bracelets, and other accessories. One of their "Collaboration Accessory" ranges is a "Gyakuten Saiban・Dai Gyakuten Saiban x MC" collaboration with Capcom. The range has rings and necklaces, which are crafted after select characters from the the Ace Attorney franchise.
These are limited edition official ace attorney merchandise made in collaboration with MATERIAL CROWN! These were only for sale in late 2017 and exclusively sold in Japan.
These are highly valuable rings made of real gold and rose gold and were sold for roughly $110 USD each. Both rings are brand new and come with unique ring boxes and certificates of authenticity.
The Phoenix Wright based ring is a US size 6 and the Miles Edgeworth ring is a size 7.
