Kawaii Hatsune Miku Ita Bag Backpack

Its quite roomy! There is no backing for pins so you have to pin directly to the bag itself, which I find weird, but its otherwise a great bag and super cute. It came pretty quickly, too, and was well packaged.

DIY insert sizing

If you want to make an insert for pins, I'd reccomend using a piece of cardboard around 29cm wide and around 22cm tall (this does obstruct the velcro used to close the display window but it doesn't really matter or affect the way the bag works). Round out the bottom corners little by little and see what fits, and them cover it with a fabric in the colour of your choice (I used a pink pajama shirt I thrifted). Personal review, the bag itself is wonderful and it brings many excited "omg is that miku!?" comments from mostly younger teenagers. I keep a pack of hatsune miku stickers in the bag to hand out to people who compliment it :)

PERFECT
