While some folks are oblivious to the perils of throwing out sensitive documents, others are quite serious about keeping personal data, well, personal. If a paper shredder is just too gadgety for your home, Plus has a solution to help you prevent ID theft.

The Plus ID Theft Prevention Stamp is a simple way to block out important information: account numbers, passwords, signatures — anything you wouldn't want prying eyes to see. You could even use it to keep a significant other from snooping around your credit card or phone bill. It comes with two different sized stamps so you can block your info in a single step.

The Plus stamp uses a design that claims to make any type of black text illegible, even when held up to a bright light, and it uses a waterproof, permanent ink. Clever idea, but could you save the $40 cost and just use a Sharpie?
