This chakra shield can be installed in any puppet. A mechanism inside the puppet opens its arms into a couple of segments, through which the user radiates their chakra. The chakra spreads out like a thin film and turns into a protective sheet, preventing all physical attacks, and some jutsus including Iron Sand thus keeping the user safeguarded. Chiyo installs one into her own arm and into the puppet of Sasori's father and mother.
