Most sets are labeled for ages 8 years and up. The large collector replica is labeled 18 years and up and is intended for adult builders.

Product details list the sets' construction material as plastic.

Larger replicas feature lights and sound (one set lists two LED light modes and recorded quotes) and are described as lighting up with sound effects; product details specify a requirement of 3 AAA alkaline batteries (required, not included).

Adult-targeted sets are described as collector-level and are labeled "ideal for ages 18+" or "for adult collectors." Descriptions highlight higher piece counts (for example, 609 pieces), more intricate detail, and display-oriented builds.
