This is a design for a ceramic piggy bank, consisting of two identical parts. When in use, a cotton string is threaded through the circular holes on the outer edges to stitch the two halves together, forming a complete piggy bank. When the coins are full and it’s time to withdraw money, the cotton string can be untied to remove the coins inside. The string can be styled in various ways around the perimeter of the piggy bank, creating different patterns and aesthetic effects, and it can also be in different colors to complement or contrast with the surrounding environment. The two parts of the piggy bank are completely symmetrical, which means that only one mold is needed for the production process.
