The Impossible Dovetail Puzzle Box

$ 17.95 USD
Tax included.

 Solid wood
 Secret cavity
 Magnets (because who doesn't love magnets)

This is a deceptively tricky puzzle box. It has a small cavity inside which is big enough to hide a secret message or even a small item. 

Stump your players with a box that appears to be impossible to open. It's a great challenge for a session and a super reveal for a secret message!



  1. Find the ball bearing. Wiggle the two halves of the box whilst examining the corners until you find the one with the ball bearing. This is what prevents it from moving.
  2. Invert and hit that corner on your hand. Hold the box with the red side down and hit the corner with the ball bearing firmly against the palm of your hand. You should hear a click as the ball bearing releases from the magnet.
  3. Slide the halves apart. The two halves of the box will now slide easily apart diagonally. To close it again, line the halves up with each other and hit the box against your hand with the red side on top.

It's Chinese New Year. Our fulfilment centre is currently working at a limited capacity due to Chinese New Year. We're shipping orders out as soon as possible but there might be a delay due to the backlog.

Covid-19 has brought uncertainty around the world, especially in transport.

But, we're still shipping as normal!

That said, shipping times are a little unpredictable currently. We're using the best shipping methods available to use but please allow an extra few days for packages to arrive during this time.

Shipping normally takes 5-15 working days but can take longer during busy periods or due to unpredictable delays.
