This is 100% cotton japa mala bag or Gomukhi. Ideally The prayer beads or japa mala is held inside of this bag and then the person chants his/her mantras. It is believed that to maintain the energy and piousness of your mantras one should not perform his chants in front of everyone just like that, instead use the japa bag so that the energy of their chants is not affected by outside negative energies. This can be a wonderful addition to your spiritual goods.
