I’ve seen these around. One of my friends has one. It’s a backpack that’s so thin and made in such a way that it looks 2D/cartoon-like/fake but it’s an actual working backpack. I think the design is fun and quirky and stylish. However, people have complained that you can barely fit anything into the backpack and that it works more as an ornamental, accessory type thing rather than a backpack. So I guess here’s an example of a design that looks super awesome, but doesn’t satisfy its purpose of holding things like a backpack would. I still like it though.
