This stone coaster set features delicate, yet bold ivory and blue floral patterns. The images have been applied using a unique transfer process that allows the lighter parts of the image to become transparent, showing the beautiful color and character of the stone underneath. So much more than a decoupage technique, this process "melts" the image into the top of the tile, making the two into one smooth surface. The tiles are completely hand made and well sealed to ensure lots of use with both hot and cold beverages. They are fully backed with cork to protect your table surfaces.Each coaster measure approximately 4x4 inches square and they are completely handmade in our rural PA farm studio using the finest Italian marble.Please leave 7-14 days for production of your coasters. If you need your order by a certain date, please send us a message and we can make it happen!The coasters are not dishwasher safe but can be wiped clean with a damp cloth, as needed.
