Tobi´s/Sasori´s Akatsuki Ring - Naruto

This ring is originally owned by Sasori, but later ownership passed to Tobi, who becomes the leader of the Akatsuki and is also a very mysterious character as he always wears a mask. Sasori is a puppeteer from Sunagakure and is also a member of the Akatsuki. Sasori is always disguised as an old doll, which means that hardly anyone knows his true form. He has also transformed his body into a puppet in order to be able to live as numb and eternal a life as possible. 

The ring is made of steel and features the Kai emblem in Japanese.
