These coasters come in a pack of 6.
They are ceramic stone and the design is a starry sky blue pattern that looks like an abstract painting.
If your glass has condensation drops the coaster is made so it absorbs quickly so there is no leakage on your table. The bottom of the coasters are made with cork which helps prevent any scratching. They are non slip and non stick. I found them easy to clean. They look nice and work great.
