Sealing Tag

By placing a sealing tag on an opponent or object, a substantial seal is generated that prevents the article in question from being summoned, as long as the originating tag remains intact. They can be applied to various mediums such as cloth and even sand, as demonstrated by Gaara, as well as linked together to make the effect stronger. They can also be thrown from a great distance by attaching them to kunai. The tags can be removed if the sealing process is incomplete, but once complete, removing the tag seems to be extremely difficult through normal means.

During the Fourth Shinobi World War, Maki, as well as the other shinobi tasked with sealing the reincarnated shinobi using the Cloth Binding Technique, used these tags in an effort to ensure that they could not simply be recalled and then re-summoned to the battlefield.
