With this exciting collection of N Scale structure parts, it's easy to design and build almost any brick industrial structure your layout needs. Each set comes with parts for a specific area of a building. Unlike traditional structure kits or assembled models, YOU choose the location of doors, loading docks, windows, roof style and more. Whether you're just getting started or have been modeling for years, you'll achieve outstanding results with Cornerstone Modulars because each piece is engineered for perfect fit and alignment to make assembly easy. Each set also includes basic assembly instructions with loads of illustrations and modeling tips. Just mix and match walls, doors, windows and details from the various sets - no complicated kitbashing or cutting is needed to create a one-of-a-kind industry for your layout. Parts come molded in realistic brick, window and door, concrete or roof colors so no painting is needed. But as separate parts, it's a snap to custom-paint your project if you want to. Best of all, you can use leftover parts with your next building and securely store them in the reclosable plastic packages until they're needed.
