Chicago Willis Tower Building Kit | 1:800 scale LEGO-Compatible MOC

What Is a MOC Building Kit?

• MOC stands for “My Own Creation.”
• MOC building sets are custom-designed models created by independent designers, not mass-produced official LEGO® or other major brick brand retail sets.
• They are popular among experienced builders for their unique designs, advanced building techniques, and display value.

How MOC Sets Differ from Official Retail Sets

Before purchasing, please note the following differences:

• Parts are packed in bulk
  Pieces are not sorted by building steps as in standard retail sets.
• Digital instructions (PDF)
  Instructions are provided digitally. Printed manuals are usually not included.
• More complex building process
  MOC models are generally designed for adult or experienced builders and may require patience and problem-solving.
• Equivalent part substitutions
  No printed parts, special parts, stickers, or minifigures
  When needed, these are replaced by other compatible bricks
• No retail box included
  MOC sets are shipped in protective packaging, but official retail-style boxes are not included.

Is This Kit Right for You?

MOC building sets are best suited for:

• Adult builders and brick-building enthusiasts
• Customers looking for unique, non-mainstream designs
• Builders who enjoy challenging and rewarding projects

If you prefer a simple, step-sorted building experience, official retail sets may be a better fit.

Order Cancellation & Changes

Please review our cancellation policy:

• Free cancellation within 2 hours of placing your order
• After 2 hours, the order enters processing. A 50% refund is available before shipment
• Once shipped, orders cannot be cancelled

This policy helps cover labor, handling, and custom preparation costs.

Order Processing & Fulfillment Flow

To ensure accuracy, all MOC orders are handled manually:

1. Order placed
2. Free cancellation window (within 2 hours)
3. Manual part picking and preparation
4. Packing and shipment
5. Delivery

Once manual picking begins, labor and preparation costs are incurred, which is why cancellation terms change after the initial 2-hour window.
