I asked my dad if he could make us a trunk that’s heavy (too heavy to walk off with!), and also locks, for any cards we may receive on our wedding day. This is what he came up with! It’s a trunk, with a real lock and key. Our names and wedding dates are engraved on a plate on the top that screws in. When you take the plate off, there’s a slot to put cards in. After the wedding, we can put the nameplate back, use it in our home for storage. It’s, indeed, a treasure chest (as in, I’ll always treasure it).
