Attack on Titan second season and the well-known accessory brand Material Crown, collaborate for the first time to create jewelry inspired by the popular anime series. The jewelry to be released are two types of silver rings, one based on Eren and one on Levi. Both rings carry the symbol of the Survey Corps, the "wings of freedom", colored stones, while each character's name is written in English on the inside.

Eren's ring will be silver-colored with green gems, while the Levi version will be black with blue gems. 

In addition, a gold necklace based on Eren's basement key from Attack on Titan's story line will be released. The necklace will have three white stones on the key's handle. 

Each accessory has a special box and a certificate with an image of either Eren or Levi. The accessories will be available through the Premium Bandai website and through the Material Crown website. The products will be released in August, with a price of 11,880 yen (about 95 euros) for each ring and 15,120 yen (about 120 euros) for the pendant.
