What if the pencil you were using to take an intelligence test was actually more challenging than any of the mind-bending questions? That's seemingly what inspired the Varacil mechanical pencil that arrives completely disassembled in 22 obscurely-shaped parts. It's not just some assembly required, it's all up to you.
Snapping the individual pieces out of the plastic frames and assembling them into a working pencil takes just under an hour on average, but of course if you get it together faster you're free to boast about your above-average intelligence and advanced puzzle-solving prowess. And because it takes the DIY approach like Ikea, the Varacil is just $10 since you're not subsidizing assembly line workers building it for you. It seems like a bargain, except for the fact that it's probably the least stable writing implement you'll ever use.
