Dimensions:  4 inches square.  This fun dog was actually black and white, but I used  a printing process to create a screen, and then printed the image to the glass.  He is a fun little guy--I made his nose a little longer than normal for interest.  Look at those wistful eyes?  The coasters will have bumpers on the bottom to protect your furniture.  They will come in a group of 4, wrapped with red ribbon.
