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, hanging from 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 addition to your room's interior or as a desk ornament, exuding a mysterious presence that will captivate anyone who sees it. This kit allows you to feel the fun of physics and the depth of LEGO bricks. It's perfect for yourself or as a gift that offers intellectual surprise. This is a disassembled kit that was assembled once before. (Please note: Due to packaging constraints, the instruction manual and the bags for the parts may differ from the photos, or we may send compatible parts. However, there is no change in the contents or quality of the kit, so please be aware of this.)
