Teifoc is a unique build and play system that uses real reusable bricks to create fun and elaborate structures and creations. Bricks are made of cooked clay and are safe for play. Each Teifoc kit includes one or more building drawings, but you can let your imagination create in endless ways! The cement is safe and soluble in water so that the bricks can be reused again and again. The Cement bag gives you extra mixing cement so you can continue to create your marvelous structures! To dissolve the cement, leave the building in water for 2 hours. Then rinse the bricks, leave them to dry, and start all over again using new cement. All of our products are designed, engineered and manufactured in our factory in Pfaffschwende, Germany. We make a variety of stainless steel and terracotta brick construction sets for budding builders of all different skill levels.
