Some years ago I bought an old set of silverware from a friend who doesn’t keep kosher. The silverware is stored in an old box, and has much more commercial value if stored in its original old containerbox. If I’d like to use the silverware in my kosher kitchen, I have to immerse the spoons forks etc. in boiling water. But can I store them in the old box further on?

You may store the silverware in the old box.
