they work perfectly

I got these to use in my car cup holders.

I live in the south and we have iced drinks most of the time. Even with the air conditioning they get a lot of condensation, which drips down and causes the moisture to pool up in the bottom of the cup holder. WIth these I can easily clean and dump out any excess water if I need to, but more importantly they protect the car from all that moisture damage. They have a lip on them that keeps the water inside it when I lift it out to dump it and clean it.

The set has 4 holders. They are all black and made from silicone. They easily fit into the front seat cup holders and the back seat ones.

I would buy these again so I think a five star rating is fair.
