Bricks are made of cooked clay and totally safe for play. Each Teifoc kit includes one or more building drawings, but you can let your imagination run free. Safe and soluble sand and corn-extract based mortar creates castles and landscapes. To build a new model, simply soak in water, dry the bricks and start again.
