This beautiful matte ceramic cork back coaster is 10.8 cm wide, it is wipeable and will retain depth of colour. I print the coasters at home in my workshop. The painting is inspired by my many walks with my canine companion, Hector. My boy is so clever, when I throw the ball with the thrower, he runs after it at high speed, catches it in his mouth and brings it back, putting the ball back in the thrower! So proud!
