Vinyl Lettering Use: As a joke I got a Nemo Sticker made and right before my mother had company I slipped in the house and put it in the toilet. So when her girl friends sat down Nemo was smiling up at them. Her friend freaked out.. LOL It was great. Anyhow it has been there for a year with lots of bleach and cleaning supplies on it and its still in one piece and hasn't faded at all. I would Highly Recommend it for any toilet.
