This is an AutoArt 74681 1:18 Lamborghini Aventador LP720-4 50th Anniversary Edition (Yellow Giallo Maggio). This is a Signature Series, Keychain wheel is included, and Weight: 2kg.

Some slight paint chip at the opening front edge of the bonnet but overall excellent condition with all fixtures intact.
