Original Philips HeartStart FRx training electrode pads come delivered in a plastic case. When the pads wear out, there's no need to buy a new case - just order these pads! With proper care, they'll last as long as the originals. Adult Pad Placement Guide or Infant/Child Placement Guide is not included. Placement guides are required if these pads are not being used on a manikin.
