block assembly instructions Award-winning ImagiBRICKS™ Giant Building Blocks are an enduring classic that offer endless play possibilities because they are versatile (build with them, jump over them, crash into them) and safe. Constructed of lightweight corrugated cardboard, if the blocks tumble, no one gets hurt! The blocks are printed with non-toxic inks and with their water-resistant coating are strong and durable for years of creative play. Because Imagibricks™ are “unit blocks”, they can even be used to teach basic math skills. For ages 18 months and up from Imagiplay.
