I love the shine that resin gives these coaster, a good size for any size mug that you may use.
Set of 2
Approx size: Large 12.5 x 9cm, Smaller 12 x 7.7cm
The resin I use is heat resistant up to 90 degrees centigrade, please do not put really hot cups/mugs on the coasters as it will mark them. They can be washed in warm soapy water if needed, and they will fade if left in direct sunlight even though they have UV protection
Colours will vary with different computer monitors
