Made as a paper roll in a diamond shape,the soap can be used piece by piece,making sure that every piece of soap can be adequately put on your body with no material wasted,just like how you use the paper roll.The diamond shape not only makes transportation convenient but also saves much space because they can be close to each other,leaving little interspace.After the paper roll is fixed in the container,the water can hardly attach the soap,let alone rob the surfactant which is the main cause of the foam.Once the ‘paper’ is put on the body,the water changes it into the liquid form so that it can be spread on the every corner of the body.
