About This

• Mix, Mold & Build Concrete – 12 oz of realistic, mess-free “concrete” compound lets kids pour driveways, bricks and barriers that stick together without water or waiting to dry.
• All-In-One Jobsite – Set packs a working crane, two 3-inch Little Machines vehicles, four molds, traffic accessories and a snap-fit play tray for tidy indoor or outdoor builds.
• Hands-On STEM Play – Scooping, packing and lifting strengthens fine-motor skills, spatial awareness and early engineering thinking for boys and girls ages 3 +.
• CAT-Tough Quality – Vehicles and tools are molded from heavy-duty plastic built to survive sandbox grit, driveway gravel and enthusiastic preschool crews.
• Reusable & Easy to Store – Compound never dries out and the tray doubles as a storage lid, so cleanup takes seconds and tomorrow’s build is always ready.
