Just the sort of trunk I'd want if were to go to Hogwarts. Unfortunately, the trunk I did have (for plain old muggle boarding school) was a horrid blue metal one, with a huge pink stripe around it. To make it easier when it was unloaded from the train.
Aging GALVANIZED METAL with...Lysol Toilet Bowl Cleaner! douse the bucket in the cleaner, set it out in the sun & an hour & a half later (after washing it off, of course)
