This clone, made from a small amount of ink, carrying chakra, is different from the ordinary Clone Technique in that it has actual substance and mass, making it difficult to see through. As a member of the Foundation, Sai is able to make use of the clone for missions involving surprise attacks, infiltration, and assassinations. However, experienced ninjas such as Orochimaru are able to see through this technique.
