These backpacks look like cartoons but are fully 3D

They're flying off the servers

Last week a dress blew people's minds with an accidental optical illusion, this week a bag is doing the same with a very intentional one.

JumpFromPaper makes a range of backpacks that look like the sort of satchels you'd scribble while bored in class, and in similar highlighter-esque pastel neon colours.

While they look flat from front-on, the bags are in fact as roomy as any other, and are already proving popular as a quirky way to turn heads and make an outfit look less serious.

Here's some more shots of them on the street.

And if you're still not convince of their tangibility, a view from the side.

The backpacks, which also include a version for men, cost between $89 and $149 and aren't designed to be taken too seriously.

"JumpFromPaper is a stylish accessory brand designing bags with boldness and playfulness, with an attempt to fulfill everyone’s childhood fantasy," the company says on its website.

"Colorful, quirky and always with a sense of humor, JumpFromPaper stands for the passion to make laughs, and encourages people to let their imagination go wild!"
