This papercraft is a life size Forehead Protector, a headband composed of a metal plate and a band of cloth, based on the Japanese manga series Naruto, the paper model created by Luisifer Chavez-Calderon. The size of finished model is about 160 (H) x 196 (W) x 313 (D) mm.
Forehead protectors are worn by most shinobi and are engraved with the symbol of their hidden village. Forehead protectors have been worn since at least the time of Asura Ōtsutsuki, though there was no engraving then.
Forehead protectors are usually worn as a sign of pride and fealty for one's village. Ninja consider it an honourable, important part of their tradition, and make a point of wearing it at all times, especially when sparring with a comrade from the same village. Although not wearing a forehead protector is frequently viewed as disrespectful to one's village and peers, a ninja who does not wear one may still be loyal to their village.
Some missing-nin, such as Zabuza Momochi, continue wearing their forehead protector even after they've left their village. Akatsuki members who retain their forehead protectors carve a long, horizontal scratch across the symbol, to show they have rescinded their allegiances and rejected their villages. Villagers of Amegakure aligned with Pain bear the same scratches across their forehead protectors, but remain loyal to the village; it symbolises their victory during the civil war against Hanzō.
In preparation for the Fourth Shinobi World War, Mifune designs a new forehead protector to be worn by members of the Allied Shinobi Forces. Engraved with the kanji for shinobi, it symbolises that, whereas once each ninja fought for their villages separately, they now stand united under one banner for the same cause. The members of the Alliance wear this in place of their original forehead protector. [Source: wikia]
