Great idea. The packaging is great and so are the instructions. They definitely work and make the polo collar look like new. Unfortunately, the discs attached to the underside of the collar fell off during the first wash. I was able to find three of them, but one is still missing. I'm worried about damage to the washing machine. π¬ If you're happy to spend money on a disposable product, this is for you. Finally I ordered fabric glue and used it to glue the discs to the underside of the collar and it fixed the problem.
