You might mistake this for a worn out plastic pin box, just like the one your Aunt kept in her sewing basket. In fact, it is a magic lens which lets you see through scratches to where treasures of the heart are hidden. It took some patience for my eyes to adjust, but once they did, I saw hearts everywhere.
Why don’t you try it for yourself? Don’t let the dull surface worry you; hearts are more likely to show themselves when things aren’t all perfect and shiny. That’s when they glow most strongly.
