Quadro is the life-sized construction toy. With Quadro, you can build playgrounds, forts, furniture, or anything you can imagine. Quadro assembles and disassembles easily with a twist of a key. Instructions are included to build several models or you can design your own. Each set comes with Mini-Quadro pieces so you can design a model in one-fifth scale before you build the big model. Quadro is strong and durable enough to last a lifetime. The pieces are UV-protected to resist fading from sunlight. We know of one family who bought Quadro to build a jungle gym for their young children. When they grew up and went away to college, they brought along their Quadro to build beds for their dorm rooms!
