‘Putting the coin into the jar- listen the sound of the coin landing’, it seems to be the entire traditional process of using the piggy bank. This piggy bank breaks the routine and adopts ‘Two-stage’ savings process: the first paragraph of savings: people put the coin into the top collection tank of the pig nose shape, when reaching a certain weight, the top flips and enters the second paragraph of the savings process: coins slide out from the top, through the spiral gallery and finally slides into the main piggy bank.
