It's basically just über colorful painters tape except its made out of rice paper.
You can put it on your walls, notebooks, dining ware, and just about anything else. I have yet to find some due to the fact that I live in the middle of no where...however, it has been on my mind.
But just where can you find it you ask? I am sure you could get it at your local Joanne's (ha like there is a local Joanne's where I live..) and/or target.
