Review: Perfect backpack for Miku fans who carry their entire lives around with them! - My daughter loves Miku, needed a new backpack, and refuses to use her locker at school. I was worried about the sturdiness and size but this bag RULES. It's got so much room, is very comfortable for her (even with like 80 lbs of books in it), and is holding up very, very well. 100% recommend!
Review: awesome bag! - this bag is beautiful and a must have for any miku fan! the bag comes with two main pockets, the front (the blue square area) and the main pocket. both are very spacious and fit quite a lot. there is also one miniature pocket in the main pocket which is convenient and another pocket on the opening flap of the bag (where the 01 is printed). Plus, there’s a secret pocket in the back to hide away any important things! the mesh of the flap makes it super easy to decorate with pins without compromising the bag’s fabric itself. the straps are adjustable and can be pushed out very far. this bag is a 10/10 for me
