Traditionally, toy boxes have been wooden. As we all know of course, those boxes can be such an icon of a happy childhood. Those big boxes, beautifully shaped and polished, can contain all those exciting toys in the one corner of the room that they occupy. It can be such a magical place for a child. And yet, they aren't perfect.
For one thing, those boxes aren't really portable. Not in any sense of the term that most people understand. You least need at least two people to pick one of those things up. Wooden toy boxes were wonderful things to have at one time. These days, people prefer something that's lighter. Something that's more practical.
