teifoc Marble run

Contains over 210 pieces and plans for 2 models. Complete with 5 marbles, cement, cement bowl, trowel, detailed instructions, and tools. Teifoc construction sets include real miniature bricks and a water-soluble cement mixture. Just like real masonry, you first mix the cement and then apply it to the bricks using the provided mini trowel. Children can either follow the plans or let their imagination run wild and create their own designs. The cement dries hard (like real cement), and when you're done building, simply soak it in water for 4-5 hours, wipe the bricks clean, and start over. The only thing you need to replace is the cement, which can be purchased separately. Suitable for children aged 6 and up and should be used under adult supervision.
