How are sets assigned to this age group?
This collection contains sets with a LEGO recommended minimum age of 18 or older. The 18+ label describes the intended building audience, not a requirement that adults only buy these sets.
Does every set here suit every age in the group?
No. The group organizes recommended starting ages, not a promise that every set suits the youngest builder in the group. Follow each set's exact age recommendation and safety warnings, and consider the builder's experience.
Are these sets new or used?
Each listing states its condition and what is included. Compare the individual listing before choosing a gift or a build.
