I might come back to take a swing this but I wanna say what a wonderful idea for a shop; just seeing it makes me smile lol. I also really like food art, ghibli and anime inspired especially always hit a soft spot for me.
I always feel a purse is so cumbersome even when they're little and I tend to forget things really easily. I found a fantastic phone case that doubles as a wallet so I usually just stick everything in my jean pockets. Phone/wallet in one, keys and some eyeliner in another.
