I don't see any stains, but since it's not unopened, please refrain from purchasing if you are concerned. I plan to ship via Yu-packet Post mini. I will pack it to fit within the specified size, so please be aware that I may compress it slightly. I'm selling this because I have too much merchandise and want to organize it a bit, so I'd be happy if it could reach someone who loves Chiikawa ❤︎ I offer a discount for bulk purchases. Feel free to comment! ^_^
