Creator Review
The coasters are gorgeous, a quality feel and heavy weight. They look like a precious archeological find. A rustic stone juxtaposed with a modern floral black and white print. I like the way the print goes slightly imperfect on the cut stone edges giving them a kind-of natural beauty.
They are a great product and I use them to protect the arms of my couch from hot cups of coffee. Printing is good happy with the quality.
