Please read my profile before purchasing for a smooth transaction. This is an assembly kit that uses LEGO bricks to create a fascinating "tensegrity" structure. It features a unique design that looks as if the central part is suspended in mid-air, held by chains. You can enjoy building this amazing structure with your own hands, experiencing the exquisite balance of tension and integrity. Once completed, it will be an eye-catching piece of interior decor or a desk ornament, creating a mysterious presence that will captivate anyone who sees it. This kit allows you to experience the fun of physics and the depth of LEGO bricks. It's perfect for yourself or as a gift that offers intellectual surprise. The item is brand new and unused. The block parts you will receive have never been touched, so they will arrive in a clean condition. Please rest assured. (Note: Due to packaging constraints, the instruction manual and the bags containing the parts may differ from the photos, or compatible parts may be sent. However, there will be no change in the kit's contents or quality, so please be aware of this.)
