Here is a set of 2 coasters that I hand cut out of Vermont slate and then hand paint with my designs. They are +/- 4 inches square. Three coats of a poly sealer and pump-on feet all add to the quality of these. They make fine gifts. Happy to paint larger quantities for you, we can talk about shipping, too. Coasters make great wedding favors and seating cards! Happy to make large quantities. Just ask!
