Bank is for your big money, and this piggy is for your small money. Tell your children how to manage their money well.
This is a mouse-shaped saving box for you and your children. The mouse evokes "the year of a mouse". This is an old Chinese way of calculating dates.
Gift Idea: Give it to a child who was born in a year of a mouse. (Recent years of a mouse: 2008, 1996, 1984, 1972...)
