Car coasters come plain without the design. I do offer sublimation designs for the car coaster also. Any of my designs can be used on them. Choose mug size and then leave a note of the design you need for car coasters and we will fix it for that size if there is not a car coaster size listed for the design you would like. You purchase the design separate under the design you would like. Car coasters are 2.5 round. You can purchase car coasters in bulk size 10pc,40pc and 100pc. Use the drop down bar.
