These 4" X 4" stone coasters - each a little piece of art -have an original drawing on each one. They have round felt protectors on the back. They can be created with a little sketch representing a city or a country that has meaning to you. I recently made a set for newly weds. I drew a coaster for each of the cities that they visited on their honeymoon and on the back I wrote their first names and the date. Contact me if you would like me to create a custom order for you. The cost is $8.50 EACH. They add up in weight but I can mail from one to four coasters in the small priority flat rate box for $5.80 anywhere in the US.
