I have been using band-aids with these cute characters on them since 3rd grade. I would ask my Mom to take me to a special store just to get them. I remember how they would wrap them up Japanese style at the counter, add stickers and trinkets while you paid - I luv'd the whole experience.
I always have some on hand because when you cut yourself bad enough to need a band-aid, you instantly feel better when Hello Kitty & Crew are looking back at you. I think of them as cheering me on to a scar-free recovery while telling me it's all going to be okay. They made my unfortunate run-in with a box cutter (oouch!) much less gruesome ♡
Tomodachi = friends in Japanese
p/s maybe they're also saying 'go Rafa!'
