Floppy Silicone Coasters - Retro Design Set of 6 - Funny Drink Coasters - Heat Resistant, Non-Slip Table Protectors

Great quality. Lot's of people think they are real. I used then for years and now I bought them as a gift for a friend. Suitable for every day use.

I have a new desk and don't wish to get cup marks on it - these coasters look amazing and will stop that from happening

Bought these mostly to help a mouse stay on a laptop when carrying it around - note that it's not fit for that purpose, the silicone just isn't "sticky" enough to hold the mouse (or glasses, phone, etc) in place very effectively, but it's certainly more friction than nothing. Have used them as a coaster too and they are suitable for that job. Nice floppy disk detailing. They should make single-density ones and 5 1/4" too :D.
