Adult owned! This is a wave 1 set of Transformers Classics Legends from roughly 2006/2007.  I'm the original owner - I had them on a shelf, boxed them up when I moved, and they've been in a box for over 10 years. They're clean, from a smoke-free home, and you can see how perfect the paint is.  It's like they just came out of the box.

If you have any questions or need more pictures, please let me know.
