The PlayCube Plywood slots together in less than a minute allowing your children to play for hours upon hours. Then when you need the space for adults or the the children are not around, the Playcube dismantles flat just as quickly for storage.
This is a slotted building toy made from cardboard circles. The creator says they are great for taking to a restaurant because they can be carried flat - but when put together they make a real structure. Something for kids to do while they wait.
