In the DIY process,you need not to solder the boxes.
It’s easy to assemble.
Batteries: AA Batteries (Not included)
Switch and Electronic motor (Included)
Please Note: The acrylic pieces come with protective brown paper ，You need to peel this off to reveal the glossy black surface.
Fully assembled, once you press the on switch, the box will open and turn itself off, this one comes in as you can see in the picture, can place on your coffee table or desk, each time you open the box and a little finger will close the box, a totally useless box that provides endless fun.
Turn the Useless Box on, and it will turn itself off. That’s all it does.
Amaze everyone with how technology can do incredibly simple things.
It could make cool people smile (and scares away the squares).
