Logos for sure. I'd also love a small osu! sticker for the back of my phone!
I would like a set of hitcircle stickers that go from 1 to 9. In addition to using them to decorate, you could also use them to label things like binders, or to hide them around your house and make people find all 9 stickers before telling them where the bathroom is.HAHAHAHAHAH THATS GREAT
