Used LEGO Technic Multi-Construction Trio 42023. This is an authentic LEGO product. I also have LEGO 42116 and 42121, and four non-genuine block products. The item was used by a child, so there may be minor scratches. Some blocks have come apart and will be sent in a zip-lock bag. There may also be missing parts, but I am unaware of them, so I would appreciate it if you could bid with this understanding. Shipping will be a simple packaging method, directly in a cardboard box. Please understand that it may come apart during transit. The instruction manual also has some tears. ☆Please also read my profile. I am prioritizing listing items, so the description is minimal. Please ask any questions in the comments. Shipping will be the cheapest method, with simple packaging. I will try my best to accommodate those with specific preferences or desired shipping methods, but additional fees may apply. Even after inspection, I may overlook something as I am an amateur seller. Please refrain from purchasing if you are overly concerned about details. I may cancel the transaction if I feel uneasy about the transaction based on the buyer's negative feedback.
