You can put in coins into pig's eye and put out coins from pig's nostril. The size of coin is possible until 30mm in diameter. In addition, the collected coins are separated by left and right rooms (according to each eye). The funny piggy bank is able to give pleasure to your saving life.

I was designed to print out this bank without supporters. However, I recommend to check a brim as one option.)
