Gift cards are fun to spend, but they fail to provide that instant gratification you get from a present you can play with immediately. That’s where this little gadget comes in. Called the Gift Card Puzzle Vault, it essentially seals your recipient’s present inside a clear plastic maze that must be cracked before they can get their hands on it.
The Gift Card Puzzle Vault includes a small metal ball bearing that your friends or loved ones must navigate through the plastic maze. Once completed, the interior chamber can be opened and the gift card released from the vault. If frustration overcomes them, there’s always the hammer option (as illustrated below) which should provide momentary amusement for all onlookers.
Measuring 10.5cm (4.13″) x 8cm (3.15″) x 1.5cm (0.59″), the Gift Card Puzzle Vault will fit all standard gift cards and at $4.99 from ThinkGeek, is a fun alternative to a greetings card.
