If you enjoy tormenting your family and friends then the Gift Card Puzzle Vault was made for you. If you have always longed to see your loved ones struggle unsuccessfully to open a gift, then you can get this handy gift-keeper that will keep them from opening your gift card for anywhere from a few minutes to a few hours.
It's because your gift card is enclosed inside a plastic casing with a lock, that requires you to navigate the little ball into the hole before the lock will disengage. You remember those games and how they drove you insane, don't you? Well, now you can drive your friends insane the same way, making them finish the puzzle before they can open your gift card. If it were me, I would just put the words “ha ha” over and over and over inside the card.
In all seriousness though, there isn't really a cooler way to send a greeting card, and it will be especially memorable if you card contains something like a gift certificate or money. Just leave a little of the green peeking out of the card, and imagine your loved one's faces when they realize that they'll have to either finish the maze – or get a large hammer – before they can spend their newfound green. Whatever the case, it won't be a card they'll forgot for a very long time.
