I still have my son's(28) first lego sets. We put them away many years ago in plastic zip-like bags with all the instructions in each set. Every piece is there. The new sets are so awesome now, I wish I had someone to buy them for. My smallest grandson is too small for them and I don't think I want to give him his uncles lego. I am hoping my son will have a son one day and give them to him, so guess I will hang on to them. The sets are some of the first. He never had any trouble keeping the sets together in the bags either. Of coarse he was pretty good at taking care of his things.
Just thought I would like to tell you all that.
