Let me explain: Life is too short to worry about such mundane things, I wanna enjoy my treasures. To me, there is a significant different between a collector, and a hobbyist. The collector will keep a sealed item sealed, sitting in a closet or shelf collecting dust, debris, skin particles, etc until they pass away, getting no enjoyment other than bragging rights. A hobbyist will buy a sealed item [preferable anyway] for collection reasons however the hobbyist will open it, enjoy it to it's fullest, and maintain the item and it's packaging so it remains in mint condition.
