Thank you for looking! This is a set of 6. They are the puffy, hollow type. These are overseas products, so please do not purchase if you are looking for perfection! Some are unopened, so please understand that I have not been able to check them all thoroughly. I am offering them at the lowest possible price, so please only purchase if you understand that there may be minor imperfections. - Due to the hollow interior of the stickers, crushing or dents may occur during shipping. - For the reasons above, and due to the nature of the product, returns and exchanges will not be accepted under any circumstances.
