These were very popular some years ago but have a lot of relavence again. They are great for teaching small children to handle and hold coins because of their shape, size, and color. Small kids and the elderly alike can easily hold, open, and find coins when they need them. The array of colors makes for anyone easily able to get their favorite. They are inexpensive, and fun.
You can even draw a face on them with a marker and use the opening for a mouth to entice little ones to gobble up their coins and learn to save...
