Before you buy

LEGO & Building Sets buying checklist

Use this checklist when comparing a shop listing, marketplace offer, or in-person purchase.

Confirm identity. Match the specific release and version to your collection plan, and request photos of the actual item.
Check condition and contents. Ask about damage, repairs, missing parts, and packaging. Save the seller’s written answers.
Compare like with like. Look for completed sales of the same version and similar condition; an asking price alone does not establish a sale value.
Review the whole purchase. Include shipping and any applicable charges in your budget. Read return terms and check how the item will be protected in transit.

A practical guide to LEGO & Building Sets

Identify the exact item

Ask whether complete includes figures, stickers, instructions, and spare parts. Inspect clips, hinges, transparent elements, and discoloration. Keep compatible third-party parts identified separately from the original set's pieces.

Build a collection with a clear focus

Start with a set that fits your space and build interests. Use the official instructions to check the assembly, and inventory loose purchases before mixing parts into storage.

Store and document your collection

Record dimensions, maker, version, included parts, and condition with clear photographs. Keep small accessories and original paperwork labeled with the matching item. Use a stable display with room around fragile details, and follow material-specific care instructions before cleaning or applying any product.

Reference resources

Use these sources to research identification, product details, or collection care. Check the current publisher information for rules and release details.
