Since the 2007 Transformers I have been collecting new figures. I have about two big tubs full (including a few that survived when i was a kid) siting in my shed.All are unopened. Im trying to get enough space to display them all. Its hard because my son is 4 and wants to open them and play with them. Which is the reason I keep them in the shed. My question is I see that some display them boxed and some open. Is this just a prefference or is it best to just keep them in the box?
