Preserving and Displaying Old LEGO Sets

Displaying Completed Sets

For many collectors, preserving old LEGO sets in pristine condition means showcasing them:

• Use glass display cabinets or custom shelves to protect sets from dust and damage.
• Avoid direct sunlight to prevent plastic discoloration.
• Control humidity and temperature to prevent plastic warping or brittleness.
• Showcase minifigures, accessories, and rare or nostalgic builds prominently.

Professionally preserving old sets can maintain their value and turn your collection into an inspiring conversation piece.

Restoration and Cleaning Tips

• Gently clean bricks using mild soapy water and a soft brush to restore vibrancy.
• Carefully repair loose or missing parts using compatible bricks or replacement pieces.
• Preserve original instruction manuals and packaging as they greatly increase set worth.

Selling Options

• Online marketplaces: eBay offers wide reach, while BrickLink focuses on LEGO-specific buyers.

Packaging and Shipping Considerations
