Amber Purifying Pot
The Amber Purifying Pot, or Kohaku no Jōhei, is one of the Five Treasured Tools of the Sage of the Six Paths and is similar to the Crimson Gourd in that it seals a person soul inside. The preparation is actually a little different but more simpler. The wielder must only call out to the opponent and if the opponent respond they will be sucked into the gourd. Though this is extremely simple, the gourd isn't something you can bring around everywhere. It is much larger than the Crimson Gourd.
The Amber Purifying Pot is also the only Treasured Tool that the Gold and Silver brothers did not get their hands on. Kumogakure keeps the pot for sealing away the Eight-tales in case it ever was released from it's jinchuriki.
