Deidara is known for his casual smirk and usually seeming "cool and relaxed." Usually, that is, not always. He's also known for his cool-color Akatsuki ring, bearing the kanji for "Sho" which is Japanese for "Blue." If you want to be show-accurate, wear this on the right index finger (if you have one) but you can surely wear it as you see fit! You can be as cool as Deidara with this stylish ring, just don't lose it- or anything you wear it on!
