Offered here is an absolute museum-worthy Nintendo Game & Watch: Mario's Cement Factory (model ML-102) from 1983. This specific set is in a true "time capsule" condition. Every single factory insert and component that originally came in the box has been preserved in exceptionally neat and complete condition for over 40 years. This is the ultimate 'Collector's Grade' set for the high-end Nintendo enthusiast. Condition and specifications: • The console: 100% tested and working perfectly. The LCD screen is crystal clear with no signs of bleeding or dark spots. The buttons are highly responsive and the sound is loud and clear. • Battery cover: The original red battery cover is present and clicks into place perfectly. The battery compartment is pristine and free from any corrosion. • Styrofoam inlay: Original, bright white, and fully intact with no crumbling corners. • Outer cardboard box: 100% original with all side flaps present. The box shows minor, logical age-related wear along the edges but remains very sturdy and vibrant. • Manual: The original paper instruction manual is free from creases or tears and is in excellent condition. • Rare Inserts: Includes the original yellow "Caution" leaflet and the extremely rare, unused red "Baby Safety" sticker sheet. These paper details are missing from 99% of the sets currently on the market. • Original batteries: Even the two original Maxell button cell batteries from 1983 are included! They are completely leak-free and shiny. A rare opportunity to acquire a piece of gaming history in the most complete condition possible. Please check the photos carefully to get a good impression of the exceptional quality. The set will be packed with extreme care (double-boxed) and shipped fully insured.
