value for money but they wouldn't come off my penis and I called the fire department, I give 5 stars because it was a unique experience.

It does exactly the job it should. It has good adhesive and doesn't come off easily, so you can use it as a bookmark for a long period of time. I use it daily in an office, where I use it as a bookmark in folders/files that open and close several times a day. I recommend it because it is useful and does its job correctly.
