I can't see this working unless your giftee is a big puzzle fan. But if there is plastic, and an idea, and a factory in China, someone will make it. And they have.

The Gift Card Puzzle Vault allows you slip any standard-sized gift card into the crystal-clear box. Your recipient can see their gift card but can't get it out until they navigate the rolling ball through the maze.

Once unlocked it can be reset and reused to cause countless hours of agony to your other 'friends'.

The site suggests a hammer, I would agree.
