Instead of just giving money inside a birthday card, why not slip a note into this box and watch how frustrating it can be to get it out.

The boxed frustration puzzle provides a bit of fun for the recipient (and anyone watching) as they try to open the box. Use it when giving money, gift certificates, tickets or anything else that might fit in.

Made from quality hardwood, the sturdy box can be re-used so if you get one, you can annoy other people when it's their birthday. Luckily it comes with instructions for any dunderheads who can't open it but unluckily, it doesn't come with any money in it.
